The Cake Bible
I was 16 when I decided I wanted to be a baker. I used to go to my local bookstore to pour over books as I began to learn about baking. I was too broke to buy any (at first), but this book fed me in so many ways, and eventually became one of the very first cookbooks on my shelf. It taught me precision, to have a sharp, careful eye, and how amazing one single dessert can be.
