Publisher's blurb:
From the Heights of Mount Celestia, the lowest levels of the Nine Hells, and the Infinite Layers of the Abyss come some of the most powerful and terrible individuals in all the multiverse. For many years, there have been few mortals brave or foolish enough to tread upon the domains of Angels, Demons, and Devils. Yet the same can not be said for the Inhabitants of the Great Beyond. For centuries, Angels, Demons, and Devils of all sorts have acted with impunity on the mortal plane, thinking themselves above the lowly mortal races.
Yet the bill comes due for those who commit the ultimate taboo: the coupling of mortals and otherworldly beings. For the offspring of such couplings prove just as powerful as their supernatural parentage and just as unpredictable as the mortal races have proven to be. These Sorcerers of the Great Beyond number some of the most powerful and terrifying individuals in all the multiverse, proving themselves great heroes and villains in equal measure.
