I was searching around on Amazon, looking for Halo stuff and I came across a Halo Book by Felix Cruz, published by Marvel.
Its called, “Halo:Fall Of Reach:Covenant”.
Now i’ve heard of Halo:FoR, but not with the covenant at the end.
It isnt released yet, it is released i bealive December 14th, 2011.

That’s a comic series based on the novel “The Fall of Reach” by Marvel Comics which has been coming out for a while. The Covenant is just the next part to be released.
