Lou's dad has been addicted to painkillers since an accident left him unable to work. He's a good, loving dad, but kind of useless. Lou's mother, Zoe, a successful novelist, abandoned Lou at birth and showed no interest in her until three years ago, when Lou was twelve. Their relationship since then has been strained, but when Lou's dad has a stroke, there is nowhere else for her to go while he recovers. Lou struggles to find her bearings and figure out why her mom left her all those years ago. She is convinced the answers are in Zoe's fiction, but when Lou's grandmother, Heather, appears at a reading, Lou realizes she may have misjudged her mother.
