At work, inside burning buildings, Capt. Caleb Holt lives by the old firefighter’s adage: Never leave your partner behind. At home, in the cooling embers of his marriage, he lives by his own rules. After seven years of marriage, Caleb and Catherine Holt have drifted so far apart that Catherine wishes she had never married. As the couple prepares to enter divorce proceedings, Caleb’s father challenges his son to commit to a 40-day experiment he calls “The Love Dare.” When Caleb discovers the book’s daily challenges are tied into his parents’ newfound faith, his already limited interest is further dampened. Is it too late to fireproof his marriage? Caleb Holt’s job is to rescue others, but now he has to face his toughest job ever … rescuing his wife’s heart.
