"When an injury forces K-9 officer Trey Harrison onto the sidelines, his only thought is getting back to the police force where he belongs. And he'll do anything to make that happen--even volunteer in a small waterfront community, just to please his boss. But no one ever said Trey had to enjoy it. Since the surgery that destroyed her dreams of having children, schoolteacher Erica Rowe has grown even more dedicated to her work with at-risk teens. So she doesn't need some cop with a chip on his shoulder putting the program's future in jeopardy. But when Trey finally connects with the students, Erica's heart melts. And when, in a tender moment, he admits he longs to have children, her heart breaks. She's convinced he'd be better off with someone who can give him everything, but she can't seem to shake the hope that maybe love is enough..."-- Page 4 of cover.
