Sister and brother Katie and Jacob travel across Canada and back with their two eccentric aunts, Kathleen and Mary, in a minivan named Rumblechum, with Benjamin, their stuffed monkey, sitting between them.

Rumblechum transports them through Saskatchewan, Manitoba and the huge province of Ontario, and finally back to their little grey house in Edmonton, Alberta.  Their dear calico cat Freedom is at the door to greet them, meowing with excitement and joy, and a mysterious parcel is opened.

A chapter book, the first of a planned series of young reader stories suitable for ages 3 to 12 years old. Fictional, but based on true traveling experiences.
