Dr. Evan Carter is a brilliant, brooding cardiothoracic surgeon with a reputation for being cold and unapproachable. Dr. Zahra Mitchell is a fiery, compassionate pediatric surgeon who believes in healing with heart. They were rivals in med school, lovers during residency, and then-ghosted each other after one explosive night. Now, five years later, they're forced to work side by side at Mercy Grace Hospital, and the tension is anything but professional. Old wounds resurface, sparks reignite, and soon, the only thing hotter than their arguments is the way Evan's hands feel on Zahra's skin. But when a high-stakes medical crisis forces them to confront their past, will they let pride keep them apart-or will they finally admit that some hearts are meant to beat as one?
