Seventeen-year-old Lottie Turner was born to ride bulls.

Rodeos, big dreams, dusty boots—bull-riding was her whole life. Until the accident. Until the diagnosis that changed epilepsy. Now her doctor and her family have grounded her for good. No bulls. No danger. No freedom.

Then Walker—her former best friend, first crush, and the boy who once knew every piece of her—returns to town for the summer. Walker’s supposed to be chasing stars with NASA, not mucking stalls, even if he really does want dirt, sweat, and saddles. He wants Lottie Turner and all of her wildness.

When Lottie makes a summer bucket list to find herself again, Walker’s the first to volunteer to do it with her. One item at a time, they tumble back into laughter, heat, and everything they left unsaid.

But as the sparks between them reignite, Lottie has to face the hardest truth of some risks can break you, but others are worth taking anyway.
