But her new powers mean nothing without the survival of her family, who she left behind to certain death on the Titanic.Unfortunately, rescuing them will prove far more difficult than she ever imagined. Time itself stands in her way, and it's willing to stop at no horror to prevent her from ever seeing her family again. In order to save them, Julia and Simon may have to give everything--perhaps, even, their very existence.
