Gears of war book series

I haven't really been paying attention to these and just recently found one at a books a million while traveling. I found a hardcover gears book. So far the book is good. Apparently i've been missing out on a whole series of books based on the gears franchise. I saw something on amazon earlier on what I think is the newest one titled the slab, that takes place while Marcus is in prison.
Has anyone else been reading these books? I guess i'll have to check amazon or some site to get the correct order of books so I can figure out which to read first and not get too confused on the story line if it is a continuation.

Haven't Read them, but this is the order before.
