Sheltered (Harlequin Intrigue Series #1577)

She'd always preferred handling things on her own. Until a sexy undercover agent stepped in to protect her. 

Strong and silent Holt Kingston has one mission: to infiltrate a dangerous cult with more firepower than faith. But when the compound's ruthless leader has a gorgeous former member in his sights, single-minded Holt won't rest until the mesmerizing Lindsey Pike is safe. 

After living undercover for years helping others flee, Lindsey isn't used to someone else calling the shots. Not even someone as capable and captivating as Holt. But now someone knows she's back—and wants her captured. Maybe even killed. As the cult slowly closes in on them, Lindsey can no longer hide how much Holt's protection soothes her peace of mind. And heals her wounded heart.
