Query: This book will turn on a light in your head that was dim.

When I first picked up a copy of Ishmael, I thought it would be written in the the typical "save the earth" format. I was gravely mistaken. This book should be required college reading, and without a doubt will be considered a classic within its own right. Ishmael is fast reading, and almost completely dialogue between two main characters. After you read this book, you will conscientiously divide everything in the world as "takers" and "leavers." Don't even hesitate to read this book!
