He's the grumpiest patient she's ever treated. She's the dose of sunshine that might just heal his wounded heart.

Dr. Sabrina Wu's medical skills are legendary among wolf shifters, which is exactly why the reclusive Logan Song needs her.

When Dr. Sabrina Wu arrives in the isolated mountain town of Angel Spring, she expects to find sick patients. But what she gets is a six-foot-four wall of muscle and attitude named Logan Song.

Logan expected a doctor, not Sabrina Wu. The cheerful doctor and the gruff loner billionaire couldn't be more different. As they race against time to uncover the cause of the shifter sickness, the attraction between them becomes undeniable and her relentless optimism threatens to tear down the walls around his heart.

But when the illness takes a deadly turn, their fledgling romance faces its greatest test. Can Sabrina's healing touch reach the wounded alpha beneath the growls? And will Logan let down his walls before it's too late?
