A great, fast reading book–I believe it won the 2016 Hugo for best novella.
It’s a book about children who step through portals to other worlds, and how they cope after returning.
Nancy is a great main character; in fact, my only real complaint is that the book introduces multiple POV… that don’t seem worth adding. The initial scene from Eleanor West’s POV made sense as a frame for the story, but the rest of the hopping didn’t seem worth the tradeoff–the information was staged so that Nancy soon discovered whatever the new POV character experienced.
Anyway, it’s a bit of a dark twist on returning home and finding that home falls short. Wonderfully written–it’s hard not to read it in one long gulp.
