Introverted Bicycle has lived most of her life at the Mostly Silent Monastery in Washington, D.C. When her guardian, Sister Wanda, announces that Bicycle is going to attend a camp where she will learn to make friends, Bicycle says no way and sets off on her bike for San Francisco to meet her idol, a famous cyclist, certain he will be her first true friend. Who knew that a ghost would haunt her handlebars and that she would have to contend with bike-hating dogs, a bike-loving horse, bike-crushing pigs, and a mysterious lady dressed in black. Over the uphills and downhills of her journey, Bicycle discovers that friends are not such a bad thing to have after all, and that a dozen cookies really can solve most problems.
