Destroyer of Worlds

The publisher's cover text tells pretty much what to expect in this book. You can read that first, but I think it better to come to this story cold – just let it unfold.
I'll just say that Larry Correia has created a fantasy world quite unlike any others that I have read. If you enjoy epic fantasy with lots of detailed combat, demons, wizards, an intricate plot and compelling characters, this series would be a good one to check out. (Also, you really should read the first two books in the series before this one.)
Good book, well written. 4+ stars.
