Three years after breaking up with firefighter lieutenant Jax, Sienna accidentally locks herself to her bed with a pair of pink fuzzy handcuffs and has no choice but to call 911. The man who arrives to rescue her is the last person she ever expected—her ex.
Jax mistakes the embarrassing scene for proof that she's moved on. But as old memories and hidden truths come to light, he realizes Sienna never stopped loving him. She left because she couldn't bear the fear of losing him to his dangerous job.
Just as they finally confront the past, a massive chemical plant explosion pulls Jax back into the line of duty. Faced with the possibility of losing him forever, Sienna must decide whether love is worth the risk. When fate gives them a second chance, they'll have to choose each other—and never let go again.
