She contacts Cory Matoska, a researcher who has made a lightweight space suit that is much more practical than existing models, with the one problem that because it is a single piece of fabric up to the neck gasket, no human can actually try it out — except Cent and her family, because of their ability to jump in and out of it.

When she takes a turn for the worse, Davy, Millie and Cent go to great lengths to set her up at their lodge home in the north of Canada.

She finds that she can navigate in space easily, either by jumping simply based on coordinates, or by visualizing changes to the Earth's position or relative motion.

She makes friends with a research team whose experimental satellite has failed to deploy properly by retrieving it for them.

The hostile group that has been hunting Davy and his family locates the home in Canada and blows it up, but everyone is safely evacuated just in time.

Those plans accelerate when Millie's mother takes a turn for the worse, and the family realizes that living in space would be the perfect treatment.

Cent and Davy work together to implement a modest space station, consisting of two concentric spherical balloons with straw-filled water/ice between them.
