Start with Pleasure Unbound. A fallen angel with a mean
streak and a mohawk, Hades has spent thousands of years
serving as Jailor of the Underworld. The souls he guards
are as evil as they come, but few dare to cross him. All of
that changes when a sexy fallen angel infiltrates his prison
and unintentionally starts a riot. It's easy enough to quell an uprising,
but for the first time, Hades is torn between delivering justice - or
bestowing mercy - on the beautiful female who could be his
salvation...or his undoing. Thanks to her unwitting participation in
another angel's plot to start Armageddon, Cataclysm was kicked out of
Heaven and is now a fallen angel in service of Hades's boss, Azagoth.
All she wants is to redeem herself and get back where she belongs. But
when she gets trapped in Hades's prison domain with only the cocky
but irresistible Hades to help her, Cat finds that where she belongs
might be in the place she least expected.
