Harlequin romantic suspense #2348

When a fellow forensic scientist asks for a favor, Glen Rivers Thomas has no reason to say yes--until he understands how much they have in common. Like him, Lorna Schwann has been forever marked by tragedy. She's been searching for answers about the disappearance of a young boy for years, and Lorna is willing to put herself in danger to solve the cold case that drives her. Glen gives Lorna access to his state-of-the-art lab and vows to protect her as she gets closer to the truth. But when Lorna tempts him to love again, can he give her access to his heart?
