Allegiances (The Battling McGuire Boys, Book 6) (Mills & Boon Intrigue)

Private Investigator Sullivan “Sully” McGuire has a reputation for danger. He’s spent most of his life tracking the men who murdered his parents. The one woman who sees past Sully’s predatorial pursuit is the wife he abandoned years ago. But Celia James has returned, this time with a target on her back. In order to save Celia, Sully is forced to resurrect old demons. New dangers—and dormant desires—bring Sully and Celia close...and old enemies even closer.
