My twin sister was the only person in the world I thought I'd known inside and out. Apparently, I was wrong.

Twin sisters share a unique bond, one that can't be broken by miles, time, or even death. Hannah and Hope Morton are no exception. When Hope takes her own life, Hannah loses a sister and a best friend, a catastrophe she isn't sure she'll survive herself.

With her family in ruins, Hannah is slowly disappearing, drowning in a sea of misery. Even her wild, energetic best friend can't pull her out of her grief. Desperate to help Hannah, her brother comes home from college, bringing his best friend Julian along, the first boy to break Hannah's heart. None of their efforts are enough to pull Hannah off her self destructive path, though. Julian is the only one who can get through to her, working his way into her frozen soul with cocky remarks and genuine love that warms her from the inside out.

As Hannah works to find answers, she continues to uncover new secrets and people that reveal a side of Hope she had never shared with her twin. Alone now, Hannah must make a decision of her own: move on and start a new life with the people she has left, or let the weight of her grief drag her down with her sister.
