In this return to the futuristic setting of Castle's (aka Jayne Ann Krentz) Amaryllis, casino owner Nick Chastain searches for a full-spectrum ""prism"" who can focus his psychic talents and help locate his late father's long-lost journal. The journal, which holds the key to a treasure-trove of alien artifacts, is sought by many--including a prism named Zinnia Spring. In a world where divorce is non-existent and lifetime marriages are contracted by matched-couple agencies, Nick and Zinnia are labeled unmatchable. But as they join forces to find the journal and a dangerous murderer, the laws of society cease to exist for this star-crossed pair. A riveting but squeamish climax that takes place in a maze of carnivorous plants, brings this imaginative, finely crafted tale to a splendid conclusion while setting the pace for future volumes. (July) FYI: Jayne Ann Krentz (who also writes historicals as Amanda Quick) lives in Seattle. Some of her earlier pseudonymous futuristic novels (such as Starfire) have recently been re-released under her own name.
