Rachel Wilde comes from a dimension that exists adjacent to ours. The
people there have structured their society around daemon collecting:
they locate, catch, and repair malfunctioning daemons (creatures out of
phase with our world that tempt people to do good or evil). Now Rachel
has been given two unusual assignments: 1) find a person who has been
trying to break down dimensional barriers, and 2) track down a missing
line of gatekeepers, human placeholders for a daemon that was too badly
damaged to repair. Authorities of Rachel’s world believe the missing
gatekeepers are descended from a girl who went missing from West Africa
hundreds of years ago, likely sold into slavery. With no leads to go on,
Rachel seeks help from Bach, a raving homeless man who happens to be an
oracle. Bach does put her in the path of both of her targets—but he
also lands her in a life-threatening situation. Somehow, Rachel has to
stop the criminal, reunite a gatekeeper with her stolen past, and, above
all, survive.
