In a dark dark wood by Ruth Ware

What should be a cozy and fun-filled weekend deep in the English countryside takes a sinister turn in Ruth Ware s suspenseful, compulsive, and darkly twisted psychological thriller.
"Sometimes the only thing to fear is yourself."
When reclusive writer Leonora is invited to the English countryside for a weekend away, she reluctantly agrees to make the trip. But as the first night falls, revelations unfold among friends old and new, an unnerving memory shatters Leonora s reserve, and a haunting realization creeps in: the party is not alone in the woods."
My take: I could not put this book down. I was up until 3:00 a.m. Sunday morning reading it. It is the best book I've read so far this year. I highly recommend it.
It is the perfect book for In the Dark, Dark Woods square!
