Still haunted by nightmares of her mother's death, fifteen-year-old Sienna Jones reluctantly travels to Indonesia with her father's relief team to help tsunami orphans with their post traumatic stress disorder-something Sienna knows a lot about. Since her mother's plane went missing over the Indian Ocean three years before, Sienna doesn't do anything if it involves the ocean or planes, so this trip is a big step forward. But the last thing she expects is to fall for Deni, a brooding Indonesian boy who lives at the orphanage, and just so happens to be HOT. When Deni hears a rumor that his father may be alive, Sienna doesn't think twice about running away with him to the epicenter of the disaster. Unfortunately, what they find there could break both their hearts.

For Sienna Jones, the last two years have felt like two lifetimes. Now, she’s finally starting to move on, diving headfirst into humanitarian missions with Team Hope, schoolwork, and maybe sort of even love. Things are looking up. But then he arrives on her doorstep, the boy she left behind, and the sight of him shakes Sienna to the core. Sparks fly. It's like no time has passed since she left him on the beach two years ago. Now she's torn between the new life she’s fought so hard to build, and the possibility of one she thought she’d never have. When they're both invited to join Team Hope on a mission in Cambodia, they jump at the chance to help. But when they lose their group and maybe each other, Sienna’s forced to make an impossible choice... and say goodbye to someone she loves one last time.
