Chase Harper's to-do list for senior year never included "fall in love" and "fight for your life," but things rarely go as planned. Tarnished gold and resembling a pocket watch, the counter he finds in a cave during the summer of 2011 will forever change the course of his life, leading him to the beautiful Ellie Williams and unlocking a power beyond his wildest imagination. In 1863, Ellie Williams completes school in Boston and returns to the Utah Territory only to discover that her grandfather and his counter, a treasured family heirloom, are missing. When Ellie is abducted and told she must produce the counter or die, an unexpected rescuer comes to her aid.
