When someone you love dies it feels like you loose part of your soul. Indigo lost someone and they took a big chunk of her soul with them. Now she's back at school and back in a life she's not sure she likes anymore. She wants to be normal, wants to heal, but she's crumbling on the inside where no one can see her pain. She's sick of all the looks of pity, people saying 'are you ok?', she's sick of it all, it just makes the pain more real.
She just wants to smile again.
