This was a very strong, engaging YA book. Pages flew, time zipped by. The lines are a little less clear than most YA novels–the “bad guys” aren’t twirling their mustaches, and you can understand their resistance.
The heart of the book is being caught between, and our Donovan gets this again and again. His “aw shucks” high status would feel little cheap, but it works well in YA. The tech is fun, the aliens feel alien…it’s quite enjoyable.
