Antiquities expert Jem Shaw has two lives: one during the day, when she catalogs museum artifacts and cares for her crippled, bitter mother; the other during the night, when she works with police to search for crime scene evidence. The only place Jem truly feels alive is in her dreams, where unlike real life she can pretend that she's safe and loved and wanted.

Yet when a demon warrior begins showing up in her mind each night, he draws Jem with him into her most secret, intimate fantasies. Finding the key to solving three brutal assault and murder cases, however, isn't as difficult for Jem as waking up to discover that her dream lover is very real -- as are the killers coming for both of them.
