While I have heard of a book on the Khazarites I have not yet read it.

In order to "round out" your education regarding at least some of todays occupants of the nation called Israel I suggest you read:      
The Thirteenth Tribe by Arthur Keostler.

Why not tell us about the Khazars yourself, skraeling? Go ahead, in your own words.
