Here's a the first part of a review for it. You can google up many more.
A Review of "Ishmael", By Daniel Quinn
"I first read Ishmael, by Daniel Quinn, after giving it to my sister as a birthday present. Actually, I read it before she did. I was impressed, and told her it was an incredible book. She read it, and agreed with me completely. A short time later, with my sister's permission, I loaned it to a favorite teacher of mine. She read it, and promptly ordered 30 copies for her classes to read. My "Literature of The Third World" class read it, and spent just about the rest of the year in discussion of it. Ishmael has an effect on people. It makes them think about the way they live their lives and how their society functions, and it makes them question.
As Ishmael opens, the author writes of a day in his life when he found what he thought a truly ludicrous advertisement in the personals section of a newspaper:
TEACHER seeks pupil. Must have an earnest desire to save the world. Apply in person.
This book won't let you down.
Other books I highly recommend are:
The Kite Runner
Seven Years in Tibet
The Life of Pi
