Mortal Coils is a tale of epic scope and imagination. 15 year old orphans Eliot and Fiona lived a restricted life with their aunt, until a chance meeting reveals they are the offspring of a goddess and Lucifer, Prince of Darkness.

To settle the custody of the children, the fallen angels create three temptations, and the gods fashion three trials to test the children. More than ever they need to stick together to survive and to learn how to use their budding supernatural abilities . . . for family allegiances are ever-shifting in the ancient, secret world they have entered.
