It's been three years since Sienna had to leave Deni on the broken shores of Bande Aceh, Indonesia. Three years she's spent trying to patch together her broken heart. Now a freshman at Stanford, Sienna loves her classes, and her see-you-on-the-weekend relationship with Spider is going really well - that is, until three bombs drop. One: Spider asks Sienna to transfer to his college and move in with him. Two: Sienna's father, unbeknownst to her, helped Deni get a student visa. Meaning Deni's coming to Stanford. This week. Three: That relief trip to Cambodia she's about to take? Deni's going with her. When Sienna sees Deni again, it's like she's back on that beach. And he feels the same way. How can Sienna move forward with Spider, the boy who loves her body and soul, when Deni makes her feel so incredibly alive? And after finding each other again, how can she let him go?
