Sara Wright knows better than to fall for a cop.
For Sara, an elite police dog trainer for the federal government, attractive women in uniform are an occupational hazard. But she gave her heart to a coworker once before and the battle scars from that failed relationship are still fresh. She dodges every chance at romance with the officers she trains, focusing her energy on turning out the finest handler-canine teams in the country. But when annoyingly perky, unfairly sexy Isabel Marquez arrives at Homeland Security's Northeast Regional Training facility brimming with excitement and a surprising desire to succeed, Sara's good intentions start to falter. She can't help being drawn to Isabel's enthusiasm, and, okay, her long dark hair and brilliant smile don't hurt either. Keeping their contact limited to friendship is harder than she thought. When it comes to enforcing her own rules of the heart, Sara might need to break a few for a chance at forever.
