Then, amidst all the preparations for Grantie Etta's one hundred and fifth birthday party, strange things start to happen. As a result Jack, too, must go to Canada.

Striking out on their own holds far more appeal, and despite limited funds and unexpected mishaps, they manage quite well – at first. But thanks to a bratty little brother, a dimension-travelling alien girl, and a handsome alien prince, an independent tour of the Zaidus planets is not without its complications.
