The Unbecoming of Mara Dyer meets The Fifth Wave in this chilling and explosive new series from author Kimberly Derting.

The last thing Kyra Agnew remembers is a flash of bright light. She awakes to discover that five whole years have passed. Everyone in her life has moved on—her parents are divorced, her boyfriend is in college and dating her best friend—but Kyra's still the sixteen-year-old she was when she vanished. She finds herself drawn to Tyler, her boyfriend's kid brother, despite her best efforts to ignore this growing attraction. In order to find out the truth, the two of them decide to retrace her steps from that fateful night. They discover that there are others who have been "taken," just like Kyra. But Kyra is the first person to have been returned past the forty-eight-hour taken mark. With a determined secret government agency after her, Kyra desperately tries to find an explanation and reclaim the life she once had . . . but what if the life she wants back is not her own?
