Mercenary's Perfect Mission (Harlequin Romantic Suspense)

Fleeing Samuel Grayson's cult was a risky move for Olivia Conner. So risky that the single mom left one of her children behind. What she'd seen in Cold Plains had destroyed all she believed in one heart-stopping instant. And it could get her killed.

Olivia's only option was a safe house she found with the help of ruggedly sexy mercenary Micah Grayson. But once she learned he was Samuel's twin, she dared not trust him…or the way her body reacted to his. Now the two—who'd both sworn off relationships—must embark on a deadly mission: rescue Olivia's son, take down Samuel and safeguard their hearts against love!
