Three more novels based in the Halo universe have been announced, including one that is titles Halo: Ghosts of Onyx. The first of the three novels will hit this November, while the other two will ship sometime during 2007.
I read the first three Halo novels around the time Halo 2 released for the Xbox and they were a pretty good read. The writing isn’t of the highest quality, but any Halo fan should be sucked into the storyline right from the beginning for the rich history and in-depth look at the characters of the franchise. In the meantime, fans of the series can check out the Halo Graphic Novel if they haven’t already.
The Halo novels are published by Tor and can be found in just about any bookstore in the Sci-Fi/Fantasy section.
