Bound — Devon McCormack

On the eve of the impending war between Heaven and Hell, the demon Kinzer and his mortal ally Maggie hunt for a powerful weapon that could destroy all of humanity. Devastated by the loss of his greatest love, Kinzer doesn't believe he'll ever find happiness again. But when he meets the immortal Hayde, he discovers all hope might not be lost after all. The angel Treycore's ex-girlfriend abducted his lover Kid and dragged him to the bowels of Hell. Now, Treycore searches for an entry into the immortal realm. But only one creature can assist him on his quest: Eilee, the most beautiful of the angels and another of Treycore's previous lovers. After the war between Heaven and Hell, Eilee lost her mind and went on a murderous rampage. With her guidance, Treycore descends into Hell and battles God's earliest creations as they journey to save Kid from the sadistic clutches of his villainous ex.
