Redundancies and Potentials

"All redundancies and potentials must be disposed of in accordance with Agency guidelines. This ensures that we can continue to use TimeFax to protect our communities, and better the lives of future generations. Aster works for the Agency, a private police force that uses time travel to stop crimes before they happen. Unlike most operatives, Aster and her sister Isadora can time travel without a TimeFax machine. Which would be pretty great...except that everyone, even Aster's own clone, keeps lying to her. As everything she's believed about the Agency and her life starts to unravel, Aster has to decide who to trust, if the Agency is worth saving-and whether she really wants to see the whole timeline"--Back cover.
