Twenty years ago, Leah Bannon's beloved Uncle Richard vanished without a trace. Leah, now a private investigator, begins to suspect it was murder. When she reopens the cold case, Gabriel Devlin-the man she loves but can never have-inexplicably stands in her way. Only four people know the truth about Richard's mysterious disappearance-Gabriel and three childhood friends...who have all sworn to take that secret to the grave. But a hidden enemy wants those shocking secrets brought to light...even if he has to kill to make it happen. After experiencing an unimaginable loss two years ago, Gabriel refuses to put himself through the pain of loving someone who could be gone in an instant. But as he thwarts Leah's investigation at every turn-both to keep his friends' pact and to keep her safe from danger-the sexy PI makes it impossible for him to protect his secrets...or his heart.
