Halo books

If any of you guys and gals out there love Halo and want to know more about the world of Halo, like where Master Chief(john) and the rest of the Spartans came from, how the covenant came about and what's in store for their future, then I highly recommend the Halo books. They're four books total and a graphic novel. I haven't read the graphic novel yet, but the books are really good. They follow along with the games nicely and fill many gaps and answer alot of questions that I had. Reading them made me appreciate the game more and the designers who brought this awesome work to light. I bought mine from Barnes and Noble but I'm sure Amazon carries it too.
Enjoy,
