Series Guide
Divine Apostasy
Every book in A. F. Kay's Divine Apostasy, in the right order, with where the side story slots in, the current release cadence, and where to go next.
Start here
Book one, Shade's First Rule. There is no other entry point, and the series is one continuous story with a single protagonist.
Go in knowing one thing: book one is the weakest entry in the series, and that is the main reason this series stays under-discussed. The full review makes the case at length. The short version is that book one carries the origin, a sixteen-year-old at his most sixteen, and a supporting cast that does not arrive until the back half. Every book after it is better, and the improvement is steep.
Verdict on the series
S-mid — Worth Starting.
Twelve books with no filler entry, no pointless side quest, and no character who exists to fill a scene. That consistency is the tier. What holds it below the top of the S band is peaks: the best moments here are excellent without quite reaching the highest moments of The Primal Hunter, He Who Fights with Monsters, or Defiance of the Fall.
What it does best. The Ruwen and Sift friendship, which is the most convincing two-hander in the genre and the closest thing available to Eric and Rugrat from The Ten Realms. A system with real weight that never turns into an hour of spreadsheet maintenance after a win. And abilities that sound useless on the page and turn out to be anything but, which is a much harder trick than handing the lead something obviously strong.
Where it sags. Book one, comprehensively. The opening is slower and rougher than what follows, the protagonist is written as a genuine teenager rather than a competent adult in a teenager's body, and readers who bounce do so here.

Next audiobook: Book 13 has no announced title or release date yet. Book 12 arrived in October 2025 and the series has averaged a new audiobook roughly every 8 months, a window that has already passed, so the next release could be announced any time. This line updates automatically when a date is confirmed.
Where the side material fits
Hamma's Last Prayer is the only side entry. It is numbered 6.5, co-written with B. R. Bea, and published under the Black Pyramid Legends banner rather than as a Divine Apostasy volume.
Slot it after The Sixth Rune if you want to read in numbered order. Be aware that the audiobook shipped in May 2023, three months after Shadow's Seventh Step, so the release calendar and the numbering disagree. Nothing in the main sequence depends on it.
Release cadence
Twelve audiobooks across roughly five and a half years, which averages out near six months a book. The recent gaps are longer: the last four run eight, four, seven and nine months.
Two things are worth knowing before reading that as a slowdown. Runtimes vary widely, from eleven hours to over eighteen, so a long book legitimately takes longer. And because Travis Baldree narrates the entire series, audio release dates track his recording schedule as much as the author's writing speed, which is a well-known bottleneck for the series he works on. The Kindle edition consistently lands first.
Who's who (spoiler-safe)
A. F. Kay keeps a glossary on his own site which is the authority on any of this, and which is worth a look if you want the full roster. It is also, by his own warning, full of spoilers. What follows is the short orientation version: who you meet early, why they matter, nothing you would rather find out yourself.
- Ruwen Starfield — Uru's Champion, which is not what he signed up for. His base class comes out as Worker, the one everybody looks down on, and his high Intelligence is what qualifies him to wear a Void Band. Sixteen at the start, and written like it.
- Sift — the best friend, and the best thing in the series. A seventeen-year-old Bamboo Viper Step practitioner who has spent his entire life inside the Black Pyramid and desperately wants to see anywhere else. His greatest ambition is to fly. His second greatest is to learn to whistle. Mechanically he is a lovely idea: his Center has no connections at all, which lets him sift the energy around him, and makes most magic simply slide off him.
- Hamma Blakrock — a seventeen-year-old Priestess from Uru's temple in Deepwell, which is how she meets Ruwen, and who helps him out of a bad situation and gets pulled into his considerably worse one. She is one of Uru's Hands: a handful of people marked with a small tree on the palm, tasked with doing whatever they can for the Champion. Ruwen is the only one who can see the mark. She also carries the 6.5 side story.
- Uru — the goddess who makes Ruwen her champion. Once called Eiru the Fair, she has spent over ten thousand years working on a single plan, and Ruwen is what that plan produced. Which is a lot of weight to put on a sixteen-year-old who wanted to be a Mage.
- Izac — Uru's twin brother, ruling from the capital of Malth, who wants to remake the universe on his own terms rather than hers. There is a twenty-thousand-foot mountain off his coast that exists mainly as somewhere to put his temper.
- Tremine — Head Librarian of the Deepwell Library, a Chaos Mage specialized in Void magic, and the closest thing Ruwen has to a father once his own parents vanish. Tremine adventured alongside them years earlier, and when they do not come back he is the one who steps in. A devout librarian who loves books, mentoring a boy who is about to have a great deal to do with them.
- Kysandra — an advanced Step master, spy and infiltrator, and the reason Ruwen survives being noticed. The moment other powers work out what he is, they send people to kill him. Ky is the one who intercepts them and keeps him alive through the stretch where he cannot do it himself. She also runs a spy network out of the top of the Black Pyramid.
- Crew Chief Bliz — the Worker's Lodge veteran who takes Ruwen on after the Ascension goes wrong, and whose actual job is showing him that the class he is ashamed of is not the disaster he thinks. Void Band mentor, eighty-eight-time bandball champion, owner of two bars, and a man whose drinking quests come with warnings attached.
- Big D — the Worker in charge of the Deepwell lodge, where Ruwen gets his first spells. Planning and logistics, and the other half of the argument that Worker is worth being.
- Madda and Padda Adda — Sift's parents, and between them masters of both the Viper and Bamboo Steps. They train Sift, and they eventually train Ruwen too, having watched how close the two of them are. They live in the Black Pyramid.
- Rami — a bookwyrm who bonds to Ruwen, talks to him telepathically, and is a great deal more capable than the word bookwyrm suggests.
- Fractal — the Dungeon Keeper for the dungeon outside Deepwell, a being made of moving crystal who is two inches across the first time Ruwen meets him. Also, quietly, a researcher.
How the system works
Worth knowing before book one, because the vocabulary arrives fast and the guide-to-the-genre version is short.
Spirit is the energy in everything. It is a blend of twelve Essences, each stored in one of twelve Meridians mapped onto the body. Thread Spirit through a single Meridian and you can draw just that essence out, and combining essences is how spells and abilities get built.
Fortifying is the progression ladder, and it runs in three bands: Metal (Lead, Copper, Silver, Gold), then Gem (Jade, Topaz, Sapphire, Diamond), then Divine (Angel, Archangel, Demigod, Deity). Moving between bands is slow and hard, which is the point.
The distinction the series cares about most: Cultivation draws energy from things that are not alive, like light and heat, while Harvesting takes it from living beings, which are far denser in Spirit. That difference is a moral question long before it is a mechanical one.
Is the series finished?
No. Twelve books are out, and A. F. Kay has signaled in a recent foreword that Divine Apostasy will end when the apocalypse plot Ruwen has been chasing since book one is resolved. The wider-multiverse material appearing in the late books is groundwork for a follow-up series rather than an open-ended extension of this one.
Book thirteen is close. A. F. Kay has said on a LitRPG forum that Travis Baldree is near the end of recording it and that a pre-order should appear on Amazon shortly. No date is confirmed, and I have not seen a listing yet, so treat that as an author's update rather than a schedule.
That matters for a twelve-book commitment. A planned ending is rare in long-running LitRPG, and it is the same structural promise that makes Cradle and The Beginning After the End easier to recommend than series with no visible finish line.
Where to go next
- The Beginning After the End by TurtleMe. The closest match on this site for the thing Divine Apostasy does best: twelve books without a bad one. Less explicit LitRPG machinery, same absence of filler.
- Cradle by Will Wight. Read it if the pattern here appeals, because it is the same pattern: an origin book that turns readers away, and a series behind it that is one of the best in the genre.
- The Ten Realms by Michael Chatfield. Specifically if the Ruwen and Sift dynamic is what hooked you. Eric and Rugrat are the closest equivalent anywhere.
Full reviews of each are linked from the Recommendations hub as they go live, and Divine Apostasy appears on the underrated list as the clearest case of a series hidden behind its own first book.
