Firefighter Rob McConnell doesn’t believe in love at first sight, until he meets Sierra Lawson and his common sense goes up in flames. The woman sets his heart alight the instant he meets her, and he could swear the feeling is mutual. But Sierra has one rule that makes a relationship between them unworkable—she doesn’t date firefighters. Still, Rob thinks the spark between them deserves a chance to grow and he’ll use every seductive talent he has to convince Sierra to take a chance on love. Sierra doesn’t believe in taking chances. Her late fiancé took them on the job as a cop and wound up dead. Knowing she can’t go through that kind of heartache again, Sierra vows never to date another man in a dangerous profession. But when hunky firefighter Rob bursts into her life, her list of rules looks set to burn up like dry kindling. The man is temptation personified. An affair seems inevitable. Guarding her heart? Impossible.
