It’s Oli’s 7th birthday and she’s really excited about the present she has been promised. A pink bicycle! But Oli’s special day doesn’t go to plan and she is so angry that she just screams and screams. Nothing ever seems to go right for Oli. Her first mamma drank too much alcohol and took bad medicine when Oli was just a tiny bump in her tummy. Now Oli finds numbers and spelling difficult, can’t always make her arms and legs do what she wants them to and often loses her temper. Oli is sad until the mysterious Aggie Whitchhazel sets her challenges to help her discover the good.
