Abby Faria returns from an extended vacation/work holiday in BC to discover that her friend, Maria is having marital problems, problems that are affecting her children as well. As Abby resumes her job as a bike courier, it becomes clear that Maria's troubles are bigger than she first presented and they are soon compounded with the disappearance of her son. She turns to Abby for help. As usual, as Abby tries to piece together the clues, and to help keep Maria's fish shop running, she makes new friends who help out. Alex, the woman who took over the Community Centre Bike work program for youth in Abby's absence, becomes a close friend as they work together. Handsome Dave, a fellow bicycle and coffee enthusiast, and an RCMP officer on loan to the Toronto police Force, becomes an unlikely ally as well, in the hunt for Thomas, Maria's son. As she continues to work on the case, Abby finds time to go for two or three thrilling rides through the city, develop a relationship with Dave, enjoy some excellent meals in Little Italy and Kensington Market, and learn some little known facts about pedophiles. But, the longer time passes, the more desperate the situation becomes. Ultimately Abby ends up trapped in Alex's house in Little Italy, in danger and frustrated at being unable to help Maria. This leads to an unexpected twist, a hidden room, the rescue of young Thomas, and the tragic death of a new friend, all of which bring relief, and grief, to Abby's community.
