Watch out for the birds
This richly detailed thriller starts with two hikers in the woods stumbling upon a dead body in an open cottage. A single black feather goes unnoticed at the death scene. This is an omen of more black feathers to come and the nightmare-inducing murders of crows that have been haunting me ever since. Full disclosure: I find crows unnerving in the best of times. The crows in this novel represent the absolute worst of times. I'll leave it at that.
