Give a brief summary of how the book ended and how the power of language played a huge role in it

The group nearly manages to save Minerva, but at the last minute, a driver shoots her to death. The devastated group buries Minerva and travels ten days before establishing a new camp. There Rose decides to leave and French runs after her. But before they get far they must join the others to inspect a group of strangers that the scouts have detected near the camp. Among the strangers is Isaac, Miig's half-Cree husband who he believed he had lost to the schools. The novel ends with their emotional reunion. Language plays a role because it is all about identity. Everything Frencie and the others are searching for involves identity that can be traced back to language.
