"Josie Bianci was killed years ago on a train during a terrorist attack. Gone forever. It's what her sister, Kit, an ER doctor in Santa Cruz, has always believed. Yet all it takes is a few heart-wrenching seconds to upend Kit's world. Live coverage of a club fire in Auckland has captured the image of a woman stumbling through the smoke and debris. Her resemblance to Josie is unbelievable. And unmistakable. With it comes a flood of emotions - grief, loss, and anger - that Kit finally has a chance to put to rest: by finding the sister who's been living a lie. After arriving in New Zealand, Kit begins her journey with the memories of the past: of days spent on the beach with Josie. Of a lost teenage boy who'd become part of their family. And of a trauma that has haunted Kit and Josie their entire lives. Now, if two sisters are to reunite, it can only be by unearthing long-buried secrets and facing a devastating truth that has kept them apart far too long. To regain their relationship, they may have to lose everything."--Provided by publisher.
