My So-Called Ruined Life by Melanie Bishop
Tate McCoy is sweet 16, and her life is just beginning. Unfortunately, she's got far too much to deal with, even for the child of divorced parents. That's because her estranged mother - who was an alcoholic - was murdered and her father is on trial for the crime. Thankfully, Tate seems to be on the way to figuring out how to handle it all and still have fun - well, at least partially.
Bishop opens her novel with the following compelling paragraph that sets the whole story up perfectly:
It’s one thing to lose your mom shortly before your sixteenth birthday. It’s another thing to know she was murdered. When they decide it’s your dad who did the murdering, nobody cares that you disagree. He is hauled off; you are farmed out. If you are wondering about how this could get any worse, try living with this fact: you and your mother had not been getting along—barely speaking—for almost two years.
