Intended to draw attention to the plight of abused children, Wheels of Fire focused on mother Cindy Chase's search for her son Jamie, who had been abducted by her estranged husband and kept prisoner by a religious cult. An epilogue to the story provided several hotline help numbers.

Wheels of Fire was later reprinted in the omnibus edition The Otherworld, which was made available in e-text format as part of Baen Books' freely-redistributable CD-ROM program, on the disc included with initial hardcover printings of Mercedes Lackey and Roberta Gellis' This Sceptre'd Isle.
