Dr. Georgia Laurence’s patient is going to die without an immediate heart transplant, and a rare blood type makes a donor nearly impossible. There’s a sliver of hope when she learns about a clinical trial right at her hospital. The only problem is the stem cell researcher is Dr. Matt Mancini, a man from her past who has absolutely no reason to help her.

Matt could soon be sharing the cure for heart disease with the world and can’t risk using such a sick patient as his first human candidate. While his attraction to Georgia tempts him to reconsider, the stem cells are stolen and his career is jeopardized.

Georgia and Matt must work together to save his study before her patient dies. As they get closer to the truth, they find the thief will stop at nothing, not even murder, and they’ll have to decide what matters most: her patient, his study… or their lives.
