I came across this book while I was away at sleepaway camp for the first time at Vasser Collage. One of my older friends, Ashley, was reading this book and I got interested. I spent my remaning [$$$] on this book, and let me tell you! This book is so much more than just a textbook, it helped me explore, for the first time, the world of DNA. Now I am usinf this book for a biography of Abraham Lincoln, and its helping drasticly. Now I am even more sure that when I grow up, I want to be an epidemiologest. If I could choose any book for a favorite, this would be mine! I would highly recomend this book for anyone whose careeer path is similar to mine, of anyone skilled in the medical feild, or anyone looking for a long, interesting, read.
