If you like mythology, Gifts from the Gods: Ancient Words & Wisdom from Greek & Roman Mythology by Lise Lunge-Larsen might be of interest to you. This is a graphic dictionary of words that can be traced back to their use in mythology. Everyone knows the expression 'Achilles' heel, and this book tells the story behind the expression. It also defines words like arachnid and janitor. Who would have thought that a study of mythology would lead to a dictionary.
I offer two books that give a different take on science. The first is The Science of Sherlock Holmes by E.J. Wagner. Sherlock Holmes was one of the greatest detectives ever and he always provided a logical explanation for 'who done it.' This book delves into the forensic science that supports Holmes discoveries. The second is The Physics of Star Trek by Lawrence M. Krauss. If you ever thought that it couldn't actually happen in real life, this book might have the answer for you.
The final book I want to mention today is A People's History of American Empire by Howard Zinn. We are in a political atmosphere that is full of debate and unrest. This book could be the catalyst of lots of political discussion about the concept of empire and how America fits into that concept.
