She can handle lusting after a target, but loving one might bring all of Hell to its knees.

Thou shalt not commit adultery.

It's an order Luxi never saw coming. She is the Sin of Lust, and adultery is her bread and butter. Yet for the first time, Lucifer sends her on assignment under orders to not play the seductress.

Her target? A preacher-turned-politician...who happens to be sex on legs.

Since his wife's infidelity, Grayson Bailey has avoided opening his heart to anyone. This changes when Luxi, his new intern, walks into his office. The intensity with which his heart and libido react makes for rotten timing. He is not one of those politicians. Yet nothing, not even the increasingly bold death threats in his inbox, can keep his mind—or his hands—off Luxi.

Resisting Grayson is the largest challenge Luxi has faced, and the more Lucifer dodges her questions, the more she wants to break the rules. Luxi knows the devil has an agenda and fears it involves a crazed assassin. With her heart compromised, Luxi is willing to do anything—even take on Hell itself—to save the life of the only man she has ever loved.
