Book excerpt: It's 1992 in Burnie, Tasmania and 12-year-old Justin lives alone with his mum. When she is well, Mum is perfect. She knows he likes his carrots raw and his toast cooled, and she knows how to sooth his growing pains. But when she is sick she cries uncontrollably and never gets out of bed. High school is on the horizon and Justin is bursting with adolescent energy. But his mum's mental illness hangs over him like a shadow and he feels the need to grow up fast. Told with youthful exuberance, Get Up Mum is a wildly endearing, entertaining and incredibly powerful memoir about love, family, and coming-of-age.
