Lily hasn't always had it easy, but she's never let that stop her from working hard for the life she wants. Leaving her small hometown behind, she's graduated college, moved to Boston, and started her own business. Everything seems to be falling into place.

Then she meets Ryle Kincaid—a gorgeous neurosurgeon who is assertive, stubborn, and maybe even a little arrogant. Yet, he's also sensitive and brilliant, with a soft spot just for her. Lily can't get him out of her head. But Ryle's complete aversion to relationships is unsettling. Even as she becomes the exception to his "no dating" rule, she can't help but wonder what made him this way.

As doubts about her new relationship emerge, so do thoughts of Atlas Corrigan—her first love and a link to the past she thought she'd left behind. Atlas was her kindred spirit, her protector. And when he suddenly reappears, everything Lily has built with Ryle is threatened.

With her heart torn between a past she can't forget and a future she doesn't want to lose, Lily must confront feelings she thought she'd buried. Faced with an impossible choice, which path will she choose?
