I get asked this question so many times, I’ve decided to create a page to explain the answer:
Essentially there are two groups of novels:
- Main Series:
I recommend reading the series in order. Book 2 might not fully make sense if you haven’t read book 1.
The Astronomicon Universe novels are spin-offs from the main series and each is a standalone book. There is no need to read the main series first and there is no order for the Universe novels. If you wish to try out Astronomicon without committing to reading the series, then the Universe novels are a great place to start.
