School of Fury. Fury, #2

Anjie Karan came home from a war on another planet and started her sophomore year eleven days later. She brought a boy with her. Kaza has crossed a galaxy, survived a siege, and has no idea what a tater tot is. Iowa takes him the way Iowa takes everything - with total confidence and slightly wrong information. He gets a locker. He gets a schedule. He gets asked, roughly nine hundred times, where he's from.
The lie holds until homecoming. Because Anjie's best friend Kathy was born on Fury and doesn't know it. Because Matt Sorensen - homecoming king, four generations of Summit Street - carries a name that used to mean something on another world. Because the red birds in every Iowa backyard have been keeping a door for four hundred years, and somebody has finally noticed. When the sky opens over her yard and takes the treehouse with it, Anjie goes back through the door - and takes half her high school with her.
On Fury there is a school with no walls, cut into a mountain, where children are taught to hear the thread of every living thing and taught not to look. There is a loom that remembers. There is a people at the gates who lost everything and were told for sixty years that it was a story they made up. And there is a question nobody at either school can answer:What do you owe, when you cannot give it back?School of Fury is the second book in the Fury series - science fiction with corn fields, marching bands, casseroles, a treaty negotiated in two languages, and one deeply unimpressed orange cat who has filed a report about all of it.
