Frank Winston begins an investigation that widens to include the mystery of a vanished airliner that had his parents on board, as well as those of the first person who found a dead twin on her doorstep, Linda Vesprie. Together, they discover that quantum physics is even stranger than scientists had believed, and that their world and an infinite series of alternate earths are in dire peril. Neither Frank nor Linda realize they are being misled when a woman from an alternate earth asks for their help. When they discover the duplicity, it is already far too late to do anything about it. Shadowy monsters, conniving federal agents, alternate worlds and a lonely scientist racing against time to save both his world and earth make this latest offering from best selling author Darrell Bain and collaborator Barbara Hodges a page-turning adventure that strings the suspense out to the last page.
