"From the #1 New York Times bestselling creator of the acclaimed Alex Delaware series comes a tour de force standalone novel that illustrates perfectly why "Jonathan Kellerman has justly earned his reputation as a master of the psychological thriller" (People). A brilliant, deeply dedicated psychologist, Grace Blades has a gift for treating troubled souls and tormented psyches--perhaps because she bears her own invisible scars: Only five years old when she witnessed her parents' death in a bloody murder-suicide, Grace took refuge in her fierce intellect and found comfort in the loving couple who adopted her. But even as an adult with an accomplished professional life, Grace still has a dark, secret side. When her two worlds shockingly converge, Grace's harrowing past returns with a vengeance. Both Grace and her newest patient are stunned when they recognize each other from a recent encounter. Haunted by his bleak past, mild-mannered Andrew Toner is desperate for Grace's renowned therapeutic expertise and more than willing to ignore their connection. And while Grace is tempted to explore his case, which seems to eerily echo her grim early years, she refuses--a decision she regrets when a homicide detective appears on her doorstep. An evil she thought she'd outrun has reared its head again, but Grace fears that a police inquiry will expose her double life. Launching her own personal investigation leads her to a murderously manipulative foe, one whose warped craving for power forces Grace back into the chaos and madness she'd long ago fled. Praise for Jonathan Kellerman "Kellerman's psychology skills and dark imagination are a potent literary mix."--Los Angeles Times "Kellerman doesn't just write psychological thrillers--he owns the genre."--Detroit Free Press"-- Provided by publisher. "Grace Blades is a master psychologist, respected by her peers and adored by her patients. She is hardworking and highly competent, a model of self-control. But in private, Grace indulges a secret thrill-seeking darkness, pursuing danger as an escape from the regimented life she's established. Closing her eyes as she flies down the Los Angeles freeway or targeting a stranger in a hotel bar for an anonymous moment of passion, Grace craves the rush. Order by day, danger by night - the double life helps her cope with memories of a traumatic childhood, in which Grace saw her mother stab her abusive father before turning the knife on herself. But her two worlds collide when a new patient turns out to be her random conquest from the night before. He pleads for her to take him on anyway, claiming a unique connection with the foster father who raised her. She refuses. The next day, his body is found by police with only her business card to identify him. Suddenly, Grace is plunged into a web of danger and deceit that will draw her back into the dark past she fought so hard to leave behind"-- Provided by publisher.
