This is an interesting premise in an interesting world. Each section of the book is narrated by a different child – Finn, 2nd grade; Emma, 4th grade; Chess, 6th grade. Each character has a unique voice, and most of their contributions are age-appropriate. The characters’ ways of understanding and narrating the world were very well done by the author. Their dad had died several years before the book begins, and shortly after the book begins, mom leaves them in the care of a parent-friend “for a couple of days.” The children quickly learn that mom has no intention of returning.
I do sort of tire of books whose main premise is that “mom and dad are missing and us kids have to solve all the adult problems.” I wonder how many of these books have I read, starting from Harry Potter? There’s quite a bit of that in Ender’s Game, and To Kill a Mockingbird as well.
Although, Greta Thunberg is a real-life example of this plot-trope in action, so perhaps I should not dismiss it so readily. (Except her parents are still alive.)
I would recommend this book for young teens or grownups who love sci-fi, good plot development, and interesting worlds.
