Mogworld by Yahtzee Croshaw
I downloaded this from Amazon thinking it was a self-published type of book, but on further research, the book is published by Dark Horse, so it’s legit. The author is a game designer and a game reviewer. So he’s got some writing cred.
The story is comfortably whimsical without being wacky, and feels like a fresh perspective. Our protagonist is an undead minion, pulled from a place of light back into the world to be a grotesque henchman for an evil wizard.
The prose flows well, and the world-building is entertaining. I recommend this one for a somewhat Terry Pratchett-like read.
