Furious Thing by Jenny Downham
If only she could stop losing her temper and behave herself, her stepfather would accept her, her mom would love her like she used to, and her stepbrother would declare his crushing desire to spend the rest of his life with her. She wants these things so badly, she’s determined to swallow her anger and make her family proud.But pushing fury down doesn’t make it disappear. Instead, it simmers below the surface waiting to erupt . . . And there’ll be fireworks when it does.
