Did you know that there are about 8,000 English books listed in Amazon’s “Religious Science Fiction and Fantasy” category right now?
You can find this number by going to Amazon’s book department and selecting categories and subcategories. In this instance I chose Books>Religion and Spirituality>Literature and Fiction>Science Fiction and Fantasy. The number of search results at the top indicates the number of listings in this category.
This does include different editions and formats (print, Kindle, audiobook) for the same titles, however. Meaning the real number of unique Christian SFF titles is far smaller than 8,000.
The number of paperbacks is about 5,000. So if we exclude the numerous alternate editions of Lewis, Tolkien, and classic writers like Bunyan and Dante, and ignore the nonfiction that slipped in (mythology coloring books) should we estimate half that: 2,500?
Is that how many Christian fantasy and sci-fi books there are right now?
Using Publisher Rocket for Market Research
Amazon shows you the number of results available for specific searches like “Christian Fantasy,” but programs like Publisher Rocket by Dave Chesson do it faster, pulling the data directly from Amazon.
Amazon itself called Chesson a “Kindleprenuer,” leading to the title of his website where he shares he has “worked with many New York Times bestselling authors like Ted Dekker, Orson Scott Card, Kevin J. Anderson… [plus] multiple major publishing companies.”
It’s useful for completing market research, but there can be glitches when using this program. For instance, when I first searched “Christian Fantasy,” it told me there were 60,000 titles listed under that keyword on Amazon and 50,000 filed under the keyword “Christian science fiction.”
That seemed astonishingly high to me, and when I reached out to their team, they indicated that there was indeed a disconnect between their and Amazon’s data. A direct query into Amazon’s search bar for “Christian fantasy” produced over 200 results, which Publisher Rocket then began showing.
So when compiling the numbers below, I double checked all results by searching the terms in Amazon directly and found them to be correct. Note that because these are monthly averages, you may get different results when you search the same terms. The number of competitors should change gradually though, as new books are only published so quickly.
The State of Christian Fantasy Publishing
Here is additional data about the types of Christian fantasy books which are being published, and significantly, how many shoppers are searching for such books.
The most important columns to analyze are “Number of Competitors,” which counts the number of books using the selected keyword, and “Est. Amazon Searches/Month” which tells you how many shoppers are searching for that keyword.
Looking at the number of books competing for these keywords, we can roughly estimate that there are between 200-800 Christian fantasy books of various sub-genres currently on Amazon. That’s our supply. Goodreads users seem to agree – there are 794 books on this list “Christian Fantasy.”
What’s the demand?
These are most searched-for terms from shoppers per month:
YA christian paranormal romance: 1,586
Biblical mythology fantasy: 1,439
Christian romantasy: 1,016
Christian fantasy: 869
Christian fantasy for children: 816
Christian paranormal fiction: 639
Christian young adult fantasy: 345
Christian epic fantasy: 243
So let’s estimate that there are roughly 200-1,500 readers looking for varied Christian fantasy each month.
That’s great news for writers, authors, and publishers of Christian fantasy. At worst, supply is just keeping up with demand, and at best there’s about twice as much interest per month as the current market supplies!
That’s simplifying the data. The specific numbers do much more to show where there are gaps in the market that Christian publishers and authors can meet.
Where Demand Exceeds Supply
There’s about 7 TIMES more interest in YA christian paranormal romance per month than there are books available for such readers. And about 4 times more monthly demand for Christian romantasy than supply!
That first revelation surprised me. The second did not.
I was also surprised by the apparently small interest in epic and medieval Christian fantasy. That’s the “easiest” type of Christian fantasy to pull off well, and is still one of the most popular sub-genres of fantasy in the general market, so I expected the most readers to be looking for such books. But supply and demand are about equal in this area, with 211 books listed as “Christian epic fantasy” and about 243 readers looking for such titles each month.
No doubt my own preferences colored my expectations, which is why hard data is so important for approaching publishing as a business, rather than just a passion.
Let’s look at some other surprises in the data.
Ironically, the keywords authors used most frequently – “supernatural christian fantasy:” 807 titles, and “christian medieval fantasy:” 435 titles – have the least amount of search interest, at under 100 queries a month.
This tells authors that they’re not marketing their books correctly to readers. That’s what this program was designed to accomplish – to help authors pick keywords that actually match buyer intent. (That’s what the “competition score” column at the end means – it’s telling you how hard it’d be to rank for the keyword.)
There commonly exists a gap between how authors anticipate readers look for books, and how shoppers actually search for their next read.
For instance, more shoppers are searching “fantasy like Narnia” (1,500/mo) than are searching “Christian fantasy” (870/mo).
Here’s an another example: I work in publishing, so I tend to use more “exact” terminology. I searched “middle grade christian fantasy” to see how many books existed in that sub-genre. It was around the 200 mark, just like you see above under “christian fantasy for children.” However, the search numbers were abysmal, at <100. I knew there’s no way there was that little interest in middle grade christian fantasy, so I typed in other terms, and discovered the much more accurate-sounding number of 816 average searches a month for “christian fantasy for children.”
So here we see that 807 supernatural christian fantasy books exist, with less than 100 interested readers, while less than 200 biblical mythology fantasy books exist, with over 1,400 interested readers. Could it be the case that readers are using the latter term to refer to story concepts like demons and angels, while authors are using the term supernatural instead? Or do readers think of “biblical mythology” as “stories set in bible times plus magic?”
That’s a question that polling could help answer. But for the main purpose of this article, analyzing supply and demand, my point is that there does appear to be greater interest in sub-genres of Christian fantasy than just the top 2 keywords reveal.
Follow the Money
It’s also important to factor in the data about “average monthly earnings” for each keyword, because that indicates how many readers are actually buying Christian fantasy. The number of people searching a term doesn’t equal the number of people who actually made a purchase. Many people searching this term didn’t end up buying anything, while many other shoppers who didn’t start with that specific search term did make a purchase.
It’s important to note that the column “average monthly earnings” records “the estimated average monthly earnings of the top books that rank for this keyword.” In other words, the fact that “Christian fantasy” sells an average of $36,701 a month means titles like Narnia sell that much a month, not that all books listed under that keyword combined sell this much a month.
That’s good news – shoppers are spending more than $36K a month to buy Christian fantasy books. But Publisher Rocket can create better estimates for the top performers.
The State of Christian Science Fiction Publishing
Now, let’s take a look at the state of Christian science fiction. They get lumped together in the parent category “Religious Science Fiction and Fantasy,” but we can learn more by separating them out.
I also threw in a stat for Christian horror at the bottom since it gets lumped in under the category “Christian speculative fiction.”
It was easier to round out the number of available titles here, as regardless of the sci-fi “sub-genre” or “thematic” terms I used, I consistently came up with around 200 titles. That’s fewer than the fantasy titles, which does not surprise me. The highest earners in this category also make far less than in the fantasy category.
Again, the Goodreads list “Christian Science Fiction” isn’t far off that number, with 138 titles.
There seems to be much less demand for Christian sci-fi across the board, though the top search query still indicates there is 3x as much demand as supply. I must also note that shoppers do weird things.
Apparently, more readers are searching with keywords like:
A Christian science fiction: 1,646 monthly queries
Scifi books with christian plot: 746 (this keywords’s top titles earn >$15K/mo!)
Science fiction for christian: 312
Christian science fiction series: 287
Christian sci-fi fiction: 265 (compared to <100 for just “Christian sci-fi,” go figure)
Christian futuristic fiction: 245
So again, when we go a bit deeper down the rabbit hole of what shoppers are actually typing into Amazon, we see that there’s more demand than the dismal <100 searches we see for some of the more sensible terms above.
And by looking at the monthly revenue for top books, we see there are definitely more than 100 readers a month willing to purchase “christian hard scifi,” “christian science fiction for youth,” and “children christian science fiction.”
Likely, many of these purchasers searched the book titles or authors directly, which indicates word of mouth is probably a better sales tactic for Christian science fiction specifically, while more readers are evidently willing to “cold search” for Christian fantasy.
I will note another unfortunate fact, which could be skewing data. Authors, desperate to find readers who would be at all interested in their book, tend to ignore genre distinctions. For instance, I’ve seen straight up wizard, medieval fantasy books listed as sci-fi when they really shouldn’t be because authors know readers in one genre are usually interested in the other too, and they want as many views as possible.
Next Steps
If we combine all of these listings, do we reach the estimated 2,500 titles? I’m not sure if there’s a gap here, but I think we can say with confidence that the current body of Christian speculative fiction lies somewhere between 1,000-3,000 titles.
Does this fit your observations?
I’m going to keep an eye on these keywords in the coming months to track any major changes or see if the numbers remain similar.
This number is growing each year, as is reader interest and generated revenue! Amazon’s data agrees.
Considering shopper interest, it seems like the most promising paths for growth are YA Christian paranormal romance, Christian romantasy, and biblical mythology fantasy. Looking at the areas of greatest revenue production, there is potential for children’s Christian fantasy and children’s Christian science fiction as well.
I think it would be greatly fruitful for Christian speculative fiction publishers and authors with a wide reader base to initiate polling among their audiences to clarify how readers define certain sub-genres of Christian fantasy and sci-fi and verify if these expectations match up with how the books are being marketed.
For the keywords that have a decent number of searches but comparatively abysmal sales, it’d be worth asking readers how existing books have failed to motivate a purchase. For instance, there are 223 monthly searches for christian scifi space exploration which result in only a measly $13 of monthly earnings for the top title. Or 1,016 monthly searches for christian romantasy compared to only $160 of monthly revenue for the top book.
It’s possible this data is incorrect or incomplete. But it’s also possible that the Christian romantasy and space exploration books currently on the market are of poor quality, lack the necessary metadata for readers to discover them, or do not actually possess what readers want.
Also, obviously Amazon isn’t the only source of data for the book industry, but it is one of the most readily available and understandable sources, especially for indie authors and presses.
Let’s find out the answer to these questions so as authors, publishers, and industry professionals, we can create better Christian science fiction and fantasy and help readers actually find our work!
If you have data which contradicts or enhances any of these findings, I’d be incredibly grateful if you shared them. Please weigh in on the conversation so we can all make a better plan for the future. Thanks!
