Olivia is one of our favorite characters. She's an independent pig with her own strong sense of self and opinions and a fully loaded imagination. In this story Olivia is busy playing when she has to go to a soccer game. Her mother makes her a red jersey to wear but then Olivia notices her favorite toy is missing. She accuses her younger brothers until she discovers the real culprit.
All the Olivia books are drawn in black and grey with red for Olivia's clothes (and a bit of green thrown in this one).
