Bad Sister

This middle grade graphic memoir by Charise Mericle Harper, featuring illustrations by Rory Lucey, follows a young girl who undergoes a crisis of conscience, realizing that she is a "bad sister."
Meet Charise.
She's energetic, helpful, a model pet owner and full of inventions.
But she's also a bad sister. When she goes too far and breaks little brother Daniel's tooth, can she redeem herself? Is an accident really an accident if you could have stopped it?
But most importantly... What does it mean to be a good sister?
