The Marshal's Prize (Undercover Heroes #2)

Abandoned as a baby, federal marshal Mitchell Garret doesn't know his family history, or even his given name. But he's made an impressive identity for himself: hero, protector, Marine, and most recently, private investigator. Which is how he falls into Heidi Norris's life. Someone's been stealing secrets from Heidi's family-owned doughnut dynasty, SweetSpuds, and she suspects it's a relative.

Before Mitch returns to the Marshals Service, he'll take this one last case. Besides, going undercover will get Mitch closer to Heidi and her lovable son, Zack. Temporarily, that is. Mitch is ready to reclaim his life, and that means finding his real family…in Florida. Only for this P.I., what he really wants is in the last place he expects.
