This is the longest series I've ever read straight through, without a break. 54 books without another mixed in since January of 2023. I would guess around 20,000 pages, and about $500. On to the "Siege of Terra"















Ah, they're considering the Siege of Terra books to be part of the Horus Heresy arc, I thought it was a standalone. Phew, I was afraid I missed some.Faustus said:
Wiki has it at 64 books (the difference was probably novellas of short stories), and a synopsis of almost every one of them is here if reading all of the books seems a little daunting:

I'd read a couple of books in the Warhammer universe and was curious how the larger mythology came about after seeing this thread.
