In the high-stakes world of cardiothoracic surgery, the only thing more dangerous than a failing heart is falling in love.

Dr. Rose Sterling is the Chief of Cardiothoracic Surgery at one of London’s most prestigious hospitals. At forty-six, she has spent twenty years transforming herself into the perfect, unfeeling surgeon—an "Ice Queen" who operates with flawless precision and zero emotional attachment. Haunted by the tragic loss of her partner, Sarah, to a surgical error, Rose enforces strict protocols and refuses to let anyone pierce her armor.

Enter Dr. Layla Kincaid.

Brilliant, fiercely compassionate, and recently fired from Mount Sinai for breaking hospital rules to save an uninsured child, Layla is everything Rose despises in a surgeon. She is a chaotic wildcard who wears avocado-print scrub caps, holds the hands of dying patients, and trusts her instincts over the rulebook.

Forced to hire Layla out of pure desperation for her understaffed department, Rose puts the new fellow on a strict, zero-tolerance probation. But as they navigate grueling surgeries, mass casualty traumas, and the intense pressure of the operating room together, their clinical distance begins to shatter. Layla's warmth challenges Rose's frozen exterior, and the undeniable, simmering tension between them becomes impossible to ignore.

When the line between professional duty and overwhelming desire finally snaps, Rose must decide if she is brave enough to risk her carefully constructed world for a chance at living again.
