The Beat of her Heart by Emily Hayes

She fixes broken hearts—but can’t mend her own.

Ice Queen Dr. Giselle Carlisle is one of the world’s top cardiothoracic surgeons—brilliant, driven, and emotionally frozen. After a brutal betrayal, she’s built walls no one can penetrate and transferred to Phoenix Ridge for a clean slate, far from distractions.
Distractions like Dr. Addie Wolfe, the infuriatingly warm, endlessly optimistic pediatric surgeon and devoted single mom, who radiates the kind of kindness Giselle has long stopped believing in.
Addie leads with her heart. Giselle trusts only her head. Their methods—and their personalities—clash immediately, and working together should be unbearable.
But somehow, it isn’t.
Addie sees the woman behind the icy mask. And Giselle, despite herself, finds Addie’s sunshine impossible to resist.
As tension gives way to something deeper, Giselle begins to wonder: what if she’s not as unfeeling as she thought? What if love isn’t a risk—but the cure?
Can she let down her guard and risk it all for love?
