If you love sweet romances (PG-rating), look no further than Rachelle Ayala's Have a Hart series. The Harts are a family of San Francisco firefighters. Their family motto is: Heart comes first.

Cait Hart has been married to Brian Wonder for 12 years, but does she really know him? The redheaded firefighter is dependable, loyal, and kind to others, but he's never let her probe his feelings.

Brian's life is blown open when his former high school teacher and wife of a senator dies in a car crash. When a pair of blue chow dogs show up at his mountain cabin, he is forced to tell Cait his secret - the real owner of the dogs is a boy he believes is his son.

Cait and Brian are tested on the true meaning of love when the boy goes missing and authorities suspect Brian of wrongdoing. Can two lost chow dogs save this fragile and vulnerable family?
