Great!
Author has done an excellent job with this entire series, with some additional information not known or not commonly known and a few new pictures. The cost is low, and the series seems to grow overnight.
This guide can be an excellent starter for kids & adults. I feel that it is important to share with my children the early space program and the pioneering spirit and efforts of so many, Project Gemini seems to get left out of history lessons and many people's minds. I lived through the program as a spectator, but as I grew up and met some of these poineers especially the astronauts, they seem to want to talk about accomplishments during Project Gemini as being the steps to landing on the Moon.
