All Things New.
(Book)

Seventeen-year-old Jessa Gray has always felt broken inside, but she's gotten good at hiding it. No one at school knows about the panic attacks, the therapy that doesn't help, the meds that haven't worked. But when an accident leaves her with a brain injury and visible scars, Jessa's efforts to convince the world that she's okay finally crumble. Now, she looks as shattered as she feels. Fleeing from her old life in Los Angeles, she moves to Colorado to live with her dad, but her anxiety only gets worse in the wake of her accident. That is, until she meets Marshall, a boy with a heart defect whose kindness and generous spirit slowly draw Jessa out of her walled-off shell and into the broken, beautiful, real world - a place where souls get hurt just as badly as bodies, and we all need each other to heal.
