The Silent Patient by Alex Michaelides. This is one of rare books that had me jumping up and saying "wow" at the end. Wonderful plot w/twists.
Thank you for recommending this!
Look at these blurbs:
"An unforgettable―and Hollywood-bound―new thriller... A
mix of Hitchcockian suspense, Agatha Christie plotting, and Greek tragedy."―Entertainment Weekly"Impressive first novel... with an
ending worthy of a classic Agatha Christie mystery."―The Wall Street JournalApparently Brad Pitt already has the movie rights. Going on my TBP list right now!
