Shadow Redemption by Rebecca Deel

After surviving a nightmare, supermodel Ruth Monihan’s past is firmly in her rearview mirror. But when unwanted gifts threaten to drag her back into the darkness, she turns to a tall, dark, and deadly operative with fire-tested skills and courage to unmask a stalker with a lethal agenda.
Living and working in the shadows is a matter of survival for Fortress operative Ben Martin. But when the woman who rocked his world asks for help, the battle-hardened warrior walks into the limelight, triggering a cascade of events that may conclude with their deaths.
