Demon: The Seven Deadlies — Greg Stolze

Trilogy of the Fallen
'Turn over any of the rocks in Greg Stolze's mind, and be prepared to stare in wonder and fascination at the many-legged, yet disturbingly human, awfulness revealed there.'
- Kenneth Hite
"Love the Sin, Hate the Sinner"
Gaviel, a smooth-talking demon who made his way out of Hell, finds himself playing the part of Noah Wallace, son and heir apparent to a televangelist mission with bulging coffers. A perfect cover for a devil on the make! Not everything can go according to plan, however. The mad demon Avitu is looking to recruit Gaviel, while the avenging angel Usiel just wants to send him back to Hell. And all the while, the spirit of Noah Wallace is clamoring for its body back, and getting just a little stronger with every day.
Even a devil eventually pays his dues.
