VOW OF FRIENDSHIP is the story of an 11 year-old girl, Christina ("Tissy") Matthews and her group of five friends, Rachel, Tracy, Anna, Karen, and Cameron. The story follows the group of friends through their grade six school year and how each deals with peer-pressure, an awakening interest in boys, their families and each other. Tissy learns some important life lessons after being mean to a "nerdy" boy in school, egging a neighbour's house and being pressured to steal some candy. The group of friends manages to work through their many disagreements and although each member of the group is very different from the others, at the end of the school year they all take a Vow of Friendship to remain friends forever.
