I received a copy of this book for an honest review from NetGalley.
A great alternative history read for younger readers. It is marketed as a children's book, rather than YA, which is spot on. I think with some editing and paring back on the almost Mary Sue protagonist, this could step up to YA, but that would another review.
I give this book, as a children's book, four stars. It was an easy read with characters that make an impression. If you have any readers under the age of 12 that have expressed interest in alternative sci-fi, this would make an excellent gift.
