I read this for the "A Genre You Don't Normally Care For" part of my 2020 reading challenge. I'm not usually into science fiction or space or aliens, but this book was fantastic. It's still a bit hard to believe it was 6 year olds accomplishing these things, but I enjoyed the characters and the story didn't end up feeling that far-fetched. The ending surprised me, but it resolved nicely and I'm looking forward to book 2.
