Fontaine, M: Tawsi Melek Meets the Dragon Prince

Michael Winchester had no idea moving to Texas would mean he'd be possessed by the Devil and knocked up by an angel... the King of Angels, Tawsi Melek!
After he is owned backward and forward by the Supreme General of Heaven, Mikey finds out what it means to take command of himself by himself and unlocks the secret of the Dragon Prince, the enemy of humanity who is so jealous of him, he can't wait to show his stuff during the Halftime Show from Hell, accompanied by the most heinous drum and bugle corps of them all... the Guns 'n' Roses!
What is the secret Tawsi Melek harbors about his arch-enemy, the Adversary God, and its acolyte, the Dragon Prince, and how can an ordinary church-going boy figure it out in time to save his soul and humanity in time?
