Fool Me Once By Harlan Coben

Former special ops pilot Maya, home from the war, sees an unthinkable image captured by her nanny cam while she is at work: her two-year-old daughter playing with Maya’s husband, Joe—who was brutally murdered two weeks earlier. The provocative question at the heart of the mystery: Can you believe everything you see with your own eyes, even when you desperately want to? To find the answer, Maya must finally come to terms with deep secrets and deceit in her own past before she can face the unbelievable truth about her husband—and herself.
