A single lie becomes a defining moment in a family's life in an unforgettable novel of psychological suspense.

After being gone for two decades, Maddy's half sister, Emily, is back in town to settle their late father's estate. Emily's not the troubled girl Maddy remembers from their volatile childhood. Apparently, all is well. It can't possibly matter anymore that Maddy married Emily's first love, but the pictures Maddy finds on her husband's phone tell a different story. Suspicions of an affair are hard to ignore.

Then again, Maddy hasn't been herself lately. She's increasingly confused. She's losing items that are precious to her. She forgets where she's going. The line between what's real and unreal has become a blur. Even the damning photos have disappeared. Though her state of mind starts to become everyone's cause for concern, Maddy refuses to believe she's losing her grip on reality. But the one thing she can't deny is the secret from the past that rewrote all their lives-a secret that's ready to come out.
