Will Jones, guardian angel on probation, has been thrust under the spotlight by his unusual alliance with a demon prince and New York's newly appointed vampire king. Known as the Immortal Trinity, they were a force to be reckoned with until their demon was abducted by Hellhounds. The balance between light and dark has been thrown off kilter. The Immortal Trinity is the In-Between's best chance at making things right, but first they have to get their demon back. Will is already walking on eggshells. The Quest to the lower realms threatens his very divinity. So does the growing connection with his charge, Vixen Jane. Are they fools for hoping the quest could end in victory? One thing is certain, nothing will ever be the same after this.
