Firefighter Billy Cates might be a little rough around the edges, but no one in the Howe County Fire Department questions his dedication to saving lives and helping anyone in need. His friends and partners trust him with their lives, but everything starts to fall apart when a series of incidents threaten to derail Billy's career and the rest of his life with it.

No one knows better than paramedic Brooke Elsworth that Billy has a big heart and a big personality. They've always been friends, and when Billy's life starts to unravel, she just has to find a way to help him. She might not be able to help him when their relationship turns to something more—something neither of them is prepared to handle.

They won't be able to stop the events about to sweep their lives away and remake both of them into something they never thought possible. Can Brooke and Billy pull this runaway train back from the brink of disaster before it leaves both their lives in ruins?
