I've been just recently bemoaning the dearth of sci-fi in middle grade fiction, and this arc showing up seemed rather timely. While I meant something more like WondLa or Wrinkle in Time, this was not a terrible disappointment.

The mix of formatting, illustrations, and text seems to gear it towards younger grades, or maybe some reluctant older kids, and the plot reaffirms this. It's probably going to be a reasonable bridge book, though the size of it might intimidate some of the kids who would benefit from it most. It's funny and goofy, and doesn't have heavy handed lessons that so many books suffer from. Some of the upper middle grades might enjoy it for palate cleanser between meatier books.

Would recommend.
