When today is interchangeable with yesterday， tomorrow may never come at all.Struggling actor Peter Abbott is about to land the biggest role of his life -- and of the future， past， and present of everyone around him. His audition for Calliope Associates requires only proof of his psychic skills， no dramatic monologue. When a government needs to know what weapons its enemies are hiding or the FBI needs to find an elusive criminal， they call Calliope， a clandestine private investigation firm made up of men and women with highly developed psychic abilities.Business is booming -- until members of the group begin disappearing at the hands of fellow psychic Simon Haywood. His genius is matched only by Peter s， but Simon alone discovers a unique way to use his extrasensory skills to travel back in time， committing crimes without any trace. His trips become increasingly more dangerous than they appear on the surface. Simon s mind grows warped and paranoid as the universe strains against his tinkering. Terrified that his extracurricular voyages will be curtailed， he plans to "erase" his colleagues.But Simon s methods are not exactly cold-blooded; instead he goes back to the moment of his victims conception and prevents them from being created. Because no one in the present day recalls they ever existed， he s not caught . . . until Peter realizes what s happening. Through a lucky fluke， his life is safe for the moment， but his girlfriend is on Simon s short list， and time is running out. Simon s sociopathic travels are disrupting the universe， folding and twisting the constraints of matter to a near-breaking point and threatening to spin the entire cosmos out of control. A Fold in the Tent of the Sky takes murder into a new dimension as it races toward its electrifying， time-twisting climax.
