Unbecoming

Katie's life is falling apart: her mum's controlling, her dad's run off, she's in love with someone whose identity she can't reveal and now her estranged grandmother's turned up on the doorstep and Katie's expected to take care of her.
Soon Katie discovers she's not the only one in her family hiding the truth. If she's going to get her life back together, she's going to have to expose everyone's deepest secrets - including her own.
