Version Control - Dexter Palmer

nAlthough Rebecca Wright has pieced her life back together after a major tragedy, she can't shake a sense that the world around her feels off-kilter. Meanwhile, her husband's dedication to his invention, the causality violation device (which he would greatly prefer you not call a time machine) has effectively stalled his career--but he may be closer to success than either of them can possibly imagine. Emotionally powerful and wickedly intelligent, Version Control is a stunningly prescient novel about the effects of science and technology on our lives, our friendships, and our sense of self that will alter the way you see the future--and the present.
