Detailed, individual maps and history on the battles of World War II. It isn’t too overwhelming for the student and is an enjoyable read for the history buff. Hardback so it will ensure lots of reading and reviews, durable pages too (not those thin, flimsy, easily tearable pages!) - this book will likely stand the test of our schooling years and beyond.

I wish I was an astronaut

Format: Hardcover

Fantastic book. A detailed history of Space Exploration beginning with the history of flight. The descriptions allowed me to visualize how it all began and how it continued to move forward through the years and into the future. The illustrations, concept art, and photography opened up a world of knowledge I did not possess. I really hope I can find more books of this caliper.
