It's not often I laugh out loud while reading adult fiction, I'll smile, chuckle or even offer a little internal acknowledgement to a clever quip. Hely made me guffaw. I found myself rereading passages that I didn't quite grasp, not because of poor execution but because I was still laughing, still thinking about the hilarity of previous sentences. I'd run downstairs to share a particularly clever passage, write them down to share with friends later, then I just decided to tell them to buy a copy of this book.
Many before me have summarized the book and the Goodreads description is more than adequate so I'll just say it's a hilarious, well-written, intelligent, insightful and delicious satire.
