As a boxer, Max Cano knows the sting of a missed right hook and the redemption of a left jab if you know how to take a hit and keep moving. When Rainey Collins is thrust into his path, he recognizes the kind of blow you don't see coming-the kind that knocks the air out of you, not with pain but possibilities. Lowering his guard proves difficult. In the ring, his guard is high; in life, it's even higher. Rainey is vibrant and beautiful, and their connection is unforgettable.

No one ever made her feel like Max did-seen, wanted, alive. So, when fate places them in side-by-side cabins one summer, everything they buried surges back to life.

Between the tranquility of late-night mountain drives and cozy reading sessions together, their love reignites. Rainey quickly falls back into her feelings; every glance, every touch, drags her deeper, despite Max's clear stance against a relationship. She hopes he'll feel the same way about her as time passes, before they part ways.

Each moment Max spends with Rainey, along with their late-night conversations, slowly breaks down his defenses. The history they hold together is something magical. Despite keeping his guard up and his past buried, he finds himself unable to resist her.

Just as their hearts begin to harmonize, everything shatters.

Will the secrets of the past unravel? When and if they do, will a solitary thread stand resilient amidst the chaos, binding them together with unyielding strength?
