Debut author Cross launches a trilogy with an exciting and complex page-turner about difficult choices. Nineteen-year-old Jackson Meyer can travel in time, but he’s no Doctor Who—he can only make short jumps backward, and he can’t change anything. It’s all harmless experimentation until his girlfriend, Holly, is shot when two gunmen attempt to kidnap him. Panicked, Jackson jumps back two years and gets stuck there. The consequences of unprepared time travel and Jackson pretending to be his 17-year-old self are amusing, but as he explores his life and pursues Holly (now his girlfriend-to-be), the already gripping story escalates. Jackson discovers his father’s secret life with a shadowy government agency called Tempest, and father and son become tangled with violent rival time travelers determined to alter the course of history. As Jackson explores his powers, he has no idea which side to trust or who is trying to kill him, and failure to make the right decisions threaten worldwide repercussions. It’s a story packed with moments both tender and electric—Cross’s zippy writing and fresh plot are an exhilarating combination. Ages 14–up. Agent: FinePrint Literary Management. (Jan.)
