Remember yesterday

"Sixteen-year-old Jessa Stone is the most valuable citizen in Eden City. Her psychic abilities could lead to significant scientific discoveries--if only she'd let TechRA study her. But after they kidnapped and experimented on her as a child, cooperating with the scientists is the last thing Jessa would do. But when she discovers the past isn't what she assumed, Jessa must join forces with budding scientist Tanner Callahan to rectify a fatal mistake made ten years ago. She'll do anything to change the past and save her sister--even if it means aligning with the enemy she swore to defeat."--Amazon.
