If you like fantasy books, I would suggest any of the discworld novels (I prefer the ones about death and the wizards). They're also pretty funny. Another good Terry Pratchett book is bad omens he wrote with Neil gaiman(not sure about the spelling). It's about an angel and demon, who have become friends, and try to prevent the apocalypse. There's more to it, but I don't want to spoil anything, and I suck at explaining things.
