Going Down — Ann Somerville

For 15 years Derzo Einan rescued others from fires, floods and natural disasters. In the aftermath of a horrific event, he's left unable to help anyone, not even himself, his empathy now more of a curse. Running from his demons, Einan finds refuge in a big city, discovering an underclass of people even worse off than him. In saving one more person, will he find his own salvation?
