Satan, BTW, is based on Selina Rosen, the mind and energy behind Yard Dog Press, which publishes some wonderful books (including this series).
From "The Four Redheads of the Apocalypse":
Satan was a big fan of musicians-- and vice versa. She'd make a deal with a musician in a heartbeat. On a lark, Satan had invented disco, rap, boy bands and grunge rock. Yet her all-time greatest achievement had been the minuet. Once people touched each other while dancing, morality tumbled downhill.
The volumes (so far) of the "The Four Redheads" series, in order, are:
The Four Redheads of the Apocalypse
The Four Redheads: Apocalypse Now!
Redheads in Love!
