Paula Hawkins
[isbn]
Hawkins keeps you guessing until the very end and then still manages to make you rethink everything you thought you knew. The multiple narrators will keep you on your toes, though the storyline continuously flows along with the harrowing river that women keep disappearing into. I loved the allusions to the European witch hunts, as the book had a very witchy vibe to me from the start.
