She's guarding a borrowed heart, afraid of her uncertain future. He's locked his away, still haunted by his past. But in this simmering enemies-to-lovers romance, sparks turn to something deeper—and the connection they tried so hard to resist might become the one thing they can't live without.

Years after a life-saving heart transplant, Liv Karlsson lives in the fragile space between gratitude and fear—thankful for every heartbeat and afraid of when they might stop. Running her family's cozy Swedish bakery gives her purpose, but mounting financial pressures and the shadows of her past leave her wondering: Is she truly living . . . or simply existing?

Then Hunter moves in next door. Guarded, cynical, and annoyingly attractive, he's everything Liv avoids—and he's also unfortunately her roommate's cousin. But when he unexpectedly steps in to help her save the bakery with a new marketing plan, their reluctant partnership sparks something neither one are prepared for. He pushes her. Challenges her. Sees her. Suddenly, the girl who's spent years protecting her heart finds it racing for someone who might just understand her better than anyone ever has.

But just as Liv begins to imagine a future worth fighting for, a devastating revelation threatens to unravel everything. Now Liv must face the ultimate test: Will she find the courage to love, or will fear take it all away?
