Before I Forget by Anne Pauly

When Anne's father dies, she is left grieving a contradiction. Jean-Pierre was a man of many faces: the self-taught philosopher born into poverty; the Buddhist who marked favourite haikus with maple leaves; the old romantic who ends every evening kissing a pixelated portrait of his late wife; and the violent bully, whose alcoholism marks his family's life in terrible ways. Sorting through his belongings and making funeral preparations, Anne tries to come to terms with who and what she's lost.
Told with a quick wit and deep tenderness, Before I Forget is a tragicomic portrait of loss and a novel for anyone who's ever loved a so-called monster.
