I highly recommend the entire series to any and all sci-fi/fantasy fans. Fforde has a brilliant sense of humor along the lines of Douglas Adams.
The first book, The Eyre Affair, takes place in an alternate version of England circa 1985. The main character is a cop in the Literary Detective division who’s father can control time. There is extinct animals brought back to life (much like Jurassic Park), werewolves, vampires, time travel, traveling into books with some of the great characters from literature, a super villian with some fairly cool powers, some pretty funny alternate history bits and Fforde’s amazing ability to play on words. Some of his character names alone make me laugh every time I read them, even on multiple rereads. The series has nods to folks like T.H. White, Tolkien, and several funny Star Wars references.
The series has been described as Monty Python, meets Harry Potter and Buffy.
