The Last Unicorn by Peter Beagle

I read this book based on Patrick Rothfuss's recommendation and it fulfilled and exceeded my expectations. The book tells the story of a unicorn who accidentally discovers she's the last one left, and then embarks on a quest to find the other unicorns. It was a really delightful story, made all the better by lots of humor that gently lampoons the fantasy genre. I could see myself coming back to this delightful book time and time again.
