Detective Inspector Vincent Ruiz can’t remember how he got to the hospital. He was found floating in the Thames with a gunshot wound in his leg and a picture of missing child Mickey Carlyle in his pocket. But Mickey’s killer is already in jail. Add to this the blood stained boat found near where Ruiz was pulled from the water, and the pieces just don’t add up. Now, accused of faking amnesia and under investigation, Ruiz reaches out to psychologist Joseph O’Loughlin to help him unlock his memory, clear his name, and solve this ominous puzzle. Michael Robotham is one of the finest new thriller writers working today. Marked by vivid characters and full of unexpected turns, Lost is a hair-raising journey of vengeance, grief, and redemption through the dark London underworld

She's standing at the front door. Covered in blood. Is she the victim of a crime? Or the perpetrator? A teenage girl--Sienna, a troubled friend of his daughter--comes to Joe O'Loughlin's door one night. She is terrorized, incoherent-and covered in blood. The police find Sienna's father, a celebrated former cop, murdered in the home he shared with Sienna. Tests confirm that it's his blood on Sienna. She says she remembers nothing. Joe O'Loughlin is a psychologist with troubles of his own. His marriage is coming to an end and his daughter will barely speak to him. He tries to help Sienna, hoping that if he succeeds it will win back his daughter's affection. But Sienna is unreachable, unable to mourn her father's death or to explain it. Investigators take aim at Sienna. O'Loughlin senses something different is happening, something subterranean and terrifying to Sienna. It may be something in her mind. Or it may be something real. Someone real. Someone capable of the most grim and gruesome murder, and willing to kill again if anyone gets too close. His newest thriller is further evidence that Michael Robotham is, as David Baldacci has said, "the real deal - we only hope he will write faster."
