First there is a Before, and then there is an After. . . .

The lives of three teens—Claire, Jasper, and Peter—are altered forever on September 11, 2001. Claire, a high school junior, has to get to her younger brother in his classroom. Jasper, a college sophomore from Brooklyn, wakes to his parents’ frantic calls from Korea, wondering if he’s okay. Peter, a classmate of Claire’s, has to make his way back to school as everything happens around him.

Here are three teens whose intertwining lives are reshaped by this catastrophic event. As each gets to know the other, their moments become wound around each other’s in a way that leads to new understandings, new friendships, and new levels of awareness for the world around them and the people close by.

David Levithan has written a novel of loss and grief, but also one of hope and redemption as his characters slowly learn to move forward in their lives, despite being changed forever.--From the Hardcover edition.
