Beltaine has devoted her life to protecting mortals from demons that have managed to cross over the thin line that exists between Earth and Hell. Being half-demon and half-mortal, Beltaine has seen just about everything. Now someone is trying to take over Hell and Beltaine must work with Kalan, the sexiest angel she has ever seen. Beltaine wants Kalan, but knows that the angel is resisting the temptation she offers because of her parentage. As the two fight the evil threatening mortals, they are unable to deny what is growing between them. Kalan has been sent by the Host of Heaven on a mission to save mortals from the demons of Hell. A madman is trying to destroy the thin veil that protects mortals from the demons of Hell. Having to work with Beltaine is not something Kalan is looking forward to. First the half-mortal, half-demon woman wants to be in control of their joint mission and her curves are distracting him from the job he has been sent to do. Kalan finds himself wanting to give into the temptation that Beltaine offers, but wonders where that will leave him?

Beltaine and Kalan have completed the first part of their mission. They’ve retrieved the book for the Devil and things should be easier for them, but the situation is getting worse. The Veil continues to rip and now the Devil’s immortal life is at stake. Beltaine never thought she’d have to save the ruler of Hell from a mortal. She also never believed she’d fall in love with anyone—angel or mortal—but here she is hoping God will be kind to her just once. Kalan has learned a lot after spending time with Beltaine. The most important everything is not as it seems. Beltaine has opened his eyes to the seamier side of the world, but he’s in for the shock of his life. Will love keep this demon and her angel alive? Is their strength enough to save Hell when Heaven comes to call?
