Sing!

What did I ever do, Karma? What did I ever do to have to pay so much? But soon Brook realises that that question will never be answered, and she learns to live with it. To say the least, her life sucks. Fatherless, with a mum that can't find a job that earns enough money to feed a family of three and pay the rent, Brook falls deeper into depression with each passing day. At school, Brook seems to have picked up a stalker and made enemies with the school Barbie, Chloe, who had stolen Brook's boyfriend. The only way Brook manages to stay sane enough to keep her little sister company is by running to put herself in physical pain.
One day she meets Alba and Gin, who quickly notice something isn't quite right with the sullen, secretive Brook. What is it that haunts Brook so much every day? Can Alba and Gin pull Brook out of her depression?
Brook secretly doubts that her friends, or anyone else, will ever be able to help her again.
