After a traumatic brain injury alters a curmudgeonly psychologist’s mind—leaving him agitated and confused but obsessively observant—he enlists his reluctant son to help investigate a colleague’s mysterious suicide . . .

Twenty-three-year-old Lukas Moore has returned to his hometown of Faith, New York, and left his burgeoning acting career behind to care for his father. Dr. Richard Moore is a psychiatrist known for being nearly as misanthropic as he is brilliant, but a recent traumatic brain injury has left him dependent on his begrudgingly attentive son and has changed his worldview in unexpected ways. Attuned to the slightest detail, Dr. Moore now sees mysteries where other people see settled facts—nowhere more so than in the disappearance of his former colleague and neighbor Dr. Jason Grant.

One year ago, Jason’s shoes, watch, and car were found beside a nearby lake and no trace of him has been found since. The obvious conclusion was suicide, despite Jason’s youth, wealth, and successful career as a child psychologist. Only two people question his fate: Richard, obsessed with fragments of memory, and Misty, Jason’s younger sister and Lukas’s high school girlfriend.

When Misty asks for the Moores’ help in finding out what really happened to her brother, Lukas takes the chance to resolve his father’s obsession and to reconnect with someone he may still have feelings for. As Lukas, Richard, and Misty are drawn into the puzzle, however, they are forced to confront the secrets behind both Jason’s disappearance and Richard’s injury. Sometimes the deepest mysteries are found in the people we think we know best.
