Things are bleak in Conor O'Malley's world. He lives in England, he's bullied at school, dad's away, grandma is not too cool and his mom is dying of cancer. His escape route is the fantasy land and its thousand year old tree with three stories to share. Them aside, it's a beautifully told tale of one horrendous disease and the grief and consequences within.
