The first is Star Wars Character Encyclopedia by Simon Beecroft. This book includes a biography of the characters from the original movies as well as the newer series. If you are a Star Wars fan, this book is sure to be of interest. If you aren't a Star Wars fan, it still is very interesting to see all of the characters and the costumes and makeup.
The second book is The Physics of Star Trek by Lawrence M. Krauss. Science fiction has always seemed to be immersed and entwined with real science. Star Trek is no exception with all of the mention of space phenomenon and proton torpedoes and alien species. You don't always think about how much is real and how much is from someone's imagination. This book will help to clear up some of the mystery around the Star Trek science.
I hope you enjoy some comic culture this summer. We certainly will as we celebrate with our Comic Con.
