From the very beginning, Halo has always been more than just a game—it's an entire universe.

The Halo story spans countless worlds and millennia, populated by a diverse range of characters, species, and perspectives, telling stories of heroism, wonder, and cosmic tragedy across a broad variety of media.

Since 2001, with Halo: The Fall of Reach preceding the release of Halo: Combat Evolved, books have been one of the primary forms of exploration of Halo's deep history—from the ancient times of the Forerunners and their war with the Flood, to the grim foundations of the SPARTAN-II program and the onset of the Covenant War, to everything between and before and beyond. With such expansive lore, the question is often asked: where do I begin?

This blog shall serve as your guide to the stories of the Halo universe told in the medium of books. Perhaps there is a particular flavor of story that you’re looking for, whether it’s hard military science fiction, alien worldbuilding around ancient and epic tragedies, or perhaps there are specific characters and periods you’re interested in...

You can find it all below, with links to Simon & Schuster's website (click on either the book titles or images) where you can either start or continue to build your Halo book collection!
