Earth & Sky was a fun, easy read. This young adult story is standard fare for the genre, although I enjoyed the characters visiting historical locations. Many time travel stories feel like a heavy-handed history lesson, but not Earth & Sky. The travel concept and how the author dealt with paradoxical time travelers worked and as with many YA stories, didn’t require a lot of high-level thinking.
Earth & Sky is worthy of four stars for a fun YA sci-fi time traveler romp. YA fans will no doubt enjoy this read.
