Four of Five stars
This is definitely worth the hour it takes to get through all 62 pages.
For almost the entire book I was ready to give it 5 stars. Really, really snappy writing, so much great humor, and a story that kept getting spookier.
In true Gone Girl style, there’s a great twist that made me think of Roald Dahl‘s stories for adults. Maybe even Poecrossed with Dahl.
But then also in true Gone Girl style, Flynn takes it a couple pages too far. The twist is twisted and twisted again, and I’m pretty sure if I took the time to think about it those twists wouldn’t make much sense. In a full length book I might have taken off more stars, but for 62 pages it’s not worth the time to use a fine tooth comb. I’m just going to say that most of this story is truly a fantastic read and worth every minute I spent reading it.
Unlike some of Flynn’s other books, I wholeheartedly recommend this one.

Just out of curiosity (I myself have only read Gone Girl) which books of Flynn’s didn’t you like?
Sharp Objects is a very dark, depressing story. It’s not bad at all, just not something I’d want to read again. I listened to Dark Places as an Audiobook and thought it was excellent in that form. Gone Girl is superb because of its twist, but I think the ending went on far too long and the character development went completely awry at that point.
Overall, I’ve given all her books 4 stars, but for different reasons. I totally love parts, and then really dislike other parts.
Thanks for your thoughts. I’ll bare them in mind when I give the rest a go.
