I like in it:
1. Bold title
2. Written by a Muslim itself
3. Given me a through walk through of Islam. There are many people (like me) in world who doesn't know Islam in more than it's just followed by Muslims, an orthodox religion. But it gives some basic and useful information about Islam's origin, facts about its prophets, positives and negative sides.
4. beleive me for a non muslim (like me) it's very useful. There were situations I was standing like a stupid among Muslims when they abused my religion, my beleifs etc. This triggered idea in me that i want to know "More about Islam and then i come across this book."
5. i can say as I'm ghoing thru this book, I can speak and question some of my friends.
6. But more than this situation frankly I beleive in respecting all religions and feelings of others.
