Safe to read Halo: Evolutions before the Original Series?

I picked up Halo: Evolutions at a discount recently because I am trying to start my collection of Halo novels and was wondering if it is safe to read before I have read the books in the Master Chief Omnibus that is coming out in November.

Or if there are any stories included I should avoid. For context I have played all mainline Halo games and the first Halo Wars, so I am not worried about any spoilers that are revealed in those. Its just that the opening novel trilogy is the obvious starting point but I want to wait for the Omnibus.
