Would you walk through fire to save the one you love? Tristan Cavanagh is looking for a fresh start. A novice firefighter paramedic, he's reeling from the loss of his fiancé and from his father's recent diagnosis with a neurodegenerative disease. He's putting out fires everywhere in his personal life, and has no time--or desire--for a relationship. Single father, firefighter lieutenant, and star of the SFFD, Nick Gutierrez does it all. When he's not busy saving lives, he's doing his best to give his young daughter the world. His heart belongs to his family, and there's no room in it for romance. Sparks fly when Tristan and Nick meet during a chance encounter at a discreet club, only for the fuel to be stolen from the fire when they realize they work together. But from the embers of their attraction, they coax an agreement: a secret, carefully-negotiated, mutually-satisfying fling. They have a careful understanding: everything is on the table--except for love. But flames have a way of spreading, and when an unspeakable tragedy strikes, but Tristan and Nick must confront their hidden feelings and decide just how far they'll go for love.
