The Silent Patient by Alex Michaelides. A woman murders her husband and is found insane, and a therapist digs in to get the truth. Very twisty and fun.
Underground Airlines by Ben H. Winters. A suspense story set in a world where the Civil War never happened and slavery continues to this day. Tough topic, disturbing at times, good tale.
Quicksand by Malin Perrson Giolito. Well reviewed but I couldn’t make it through, might be due to a weak translation.
But What If We’re Wrong by Chuck Klosterman. Very thoughtful discussion of our conventional wisdom about culture, science, and other topics. We are certainly wrong about many things we believe — how are we probably wrong, where is truth likely to be found, and does it matter?
