Why we recommend it

Close quarters and a guardian who'd burn the world to keep her safe drive this stylish mafia series opener. The protector is lethal, the heroine in his orbit whether she likes it or not, and the air between them crackles. If you love a possessive hero standing between danger and the woman he can't stop wanting, this first card in a darkly glamorous suit of sin promises tension, heat, and high-stakes menace.
