Not Forgotten is an original novel based on the U.S. television series Angel.
Los Angeles is being struck by a crime wave. There seems to be no link between the victims and their cause of death - burning from the inside out. Supernatural powers seem to be involved. Angel investigates the deaths, and Cordelia tries to find a band of child thieves. Both searches lead in the same direction - a rich slumlord who is imprisoning the children's immigrant parents. Angel, Doyle, and Cordelia all have difficulties in L.A., but they realize it's much harder for these immigrants. Angel hopes to help before it is too late.
