He Loves Me, He Loves Me Hot by Stephanie Rowe
Immortally Sexy #3
Her heart may be in the right place...but her soul belongs to Satan.
Being Satan's most infamous minion is the only life Becca Gibbs has ever known. But now she's restless, sick and tired of stealing souls, and ready to break free on her own. Unfortunately, this gig isn't like any other job. Its first rule: Walk out on the Devil-and kiss your life good-bye.
Nick Rawlings is the last of the Markku, a race of fighters that broke from Hell to pull for the good. When his sister goes missing, and her ransom is the death of Satan, Nick's more than willing to take on the fight. The first step? Getting the devil's sexy right-hand helper on his side. The second? Well, if he can take his eyes-and hands-off of her, he's sure he'll think of it...
