He's a firefighter fighting for his future. She's a paramedic haunted by the past. Neither expected a spark that could set their world ablaze.

Lieutenant Tony Clark has been stuck in the same rank for far too long, and all signs point to sabotage—by none other than his own fire captain. When a rescue turns nearly fatal, Tony finds himself face-to-face with Jessica Ridley, the sharp-tongued paramedic who knows just how to push his buttons—and who also happens to be his captain's estranged daughter.

Jessica's been holding it together ever since losing her brother in a mission gone wrong. She doesn't have time for distractions, especially not the charming firefighter whose brother was part of the tragedy. But with every emergency call, every shared late-night shift, Tony begins to challenge everything she thought she knew—about grief, loyalty, and love.

As tensions rise inside Firehouse Five and danger closes in, Tony and Jessica will have to decide what's worth fighting for... and what they're willing to risk to ignite a chance at love.
