Everyone wants to know why Syd left, but the truth is, Miranda has no idea. When Miranda’s mother abandoned her as a child, Miranda had found shelter in her friendship with Syd, who wore her own motherlessness like a badge of honor. Now Miranda’s been left behind again, left to untangle the questions of why Syd left, where she is—and if she’s even a friend worth saving, all while stumbling into first love with the most unlikely boy in school. How do you take on the future when it feels like so much of your past wasn’t even real?
