Just Enemies by Sidney Bristol

Liam Keys has stayed away from the love of his life out of guilt and now he has to kidnap her. Ten years ago he shattered her fractured family and hasn’t forgiven himself. Now Prudence is the personal body guard of his number one suspect. With a ticking clock and an international incident on the horizon he’s left with no options.
Prudence Wright never thought she’d see Liam again. He ghosted her at the lowest point in her life and she hates him. Now she’s trapped in a basement and she has a pretty good idea why. Her client’s criminal husband. Prudence is determined to protect the wife and get them somewhere safe, until she’s betrayed by the one person she thought she could trust.
In an unlikely turn of events Liam needs Prudence’s help. But she wants nothing to do with him. He’ll give her the long-buried truth she’s been after for one favor and pray he survives her wrath.
