Gayle Forman is well known for her writing of teen novels that provide interesting fodder for discussion both within and outside of a classroom setting, and Where She Went is no exception. Where She Went is a companion novel to Forman's If I Stay. Both novels have Forman's recurrent themes of love, romance, heartbreak, friendship and fate. The first of the novels has Mia making the choice of whether and how to survive after a devastating accident.
Where She Went is a continuation of the story of the relationship between main characters Mia and Adam. Both musicians, Mia is a rising star at Julliard and Adam is a West Coast rock sensation. Adam returns to New York for one night in which he and Mia explore their past and present relationship and what it means in terms of their past and future relationship. There is an absolutely beautiful quote where Adam realizes the importance of both their relationship and their love.
But I'd do it again. I know that now. I'd make that promise a thousand times over and lose her a thousand times over to have heard her play last night or to see her in the morning sunlight. Or even without that. Just to know that she's somewhere out there. Alive.
Particular themes found in Where She Went are hope, reunion, anger, and reconciliation. These stem from their previous relationship, the decision of Mia to attend Julliard and Adam to go to the West Coast where he finds both popular fame and a new girlfriend, and his return and exploration of his relationship with Mia.
