Now, her life's upended by a prophecy that foretells her unusual destiny. How can someone travel through time? When Ainsley encounters two witches with enlightening answers, it only leaves her more uncertain. And then there's the handsome, dark-haired English surgeon whose entrancing smile and amusing charm prove irresistible. But Ainsley senses he's well-entangled in the mystery now divining her life. Caldwell Prescott's been sent to 1863 Gettysburg as an army surgeon. However, even with a major battle imminent, his true assignment's far more complicated and dangerous.
