Umbel (Terminal Trilogy #3)

Fourteen years after Heaven and Hell finally find peace, a hellhound finds himself worrying he might be somehow special in a chaotic city on the edge of revolution and the brink of war. Unsure of who he is, he only finds solace in a few words: "You are not who you could have been." His life soon features a band of teen rebels, a ghost, and hell politics.

sequel to radicle and terminal, stands on it's own only for the first 10 chapters. Would suggest reading AT LEAST radi first, but unfortunately termi is also recommended. Go ahead and jump in blind if you want though, what do I care.
