What Readers Are Saying:

What I really appreciated about “Are You a Monster or a Rock Star” was that complicated scientific concepts were explained and presented in a manner that was not only easy to comprehend, but also conversational with a dash of “nerdy” humor.

Everywhere I turn I hear people lecturing that my energy drinks are going to kill me one day. I bought this book expecting to read the same thing, but it turned out to be so much more. It was very refreshing to learn about the topic from an author that did not appear to have an agenda. She wrote about facts. She covers positives as well as negatives about energy drinks.
