Jem
Brought up in the Institute in Shanghai, Jem's parents were killed by a demon who allowed Jem to live—but with a terrible price to be paid. Frail and silver-haired, Jem seems an unlikely demon-killer, but his skills and swift intelligence make him a formidable foe. He finds a kindred spirit in Tessa as both of them feel they are torn between two worlds, neither belonging completely to one or to the other. As Jem's affection for her grows, will Will have to hurt the only person in his life he's ever seemed to care about?
