Halo: The Fall of Reach (Halo #1)

As the bloody Human-Covenant War rages on Halo, the fate of humankind may rest with one warrior, the lone SPARTAN survivor of another legendary battle . . . the desperate, take-no-prisoners struggle that led humanity to Halo--the fall of the planet Reach. Now, brought to life for the first time, here is the full story of that glorious, doomed conflict.

While the brutal Covenant juggernaut sweeps inexorably through space, intent on wiping out humankind, only one stronghold remains--the planet Reach. Practically on Earth's doorstep, it is the last military fortress to defy the onslaught. But the personnel here have another, higher priority: to prevent the Covenant from discovering the location of Earth.

Outnumbered and outgunned, the soldiers seem to have little chance against the Covenant, but Reach holds a closely guarded secret. It is the training ground for the very first "super soldiers." Code-named SPARTANs, these highly advanced warriors, specially bioengineered and technologically augmented, are the best in the universe--quiet, professional, and deadly.

Now, as the ferocious Covenant attack begins, a handful of SPARTANs stand ready to wage ultimate war. They will kill, they will be destroyed, but they will never surrender. And at least one of them--the SPARTAN known as Master Chief--will live to fight another day on a mysterious and ancient, artificial world called Halo. . . .

Halo: First Strike (Halo #3)

 The Human-Covenant war rages on as the alien juggernaut sweeps inexorably toward its final goal: destruction of all human life!

Halo has been destroyed, and the threat it posed to sentient life, neutralized. But victory has come at a terrible cost for the UNSC. Thousands of valiant soldiers fell in the battle to prevent the alien construct from falling into the enemy’s clutches.

Now, everything depends on the Spartan known as the “Master Chief.” Yet even with the aid of the artificial intelligence Cortana, the Master Chief will be hard-pressed to rescue survivors and evade the Covenant ships patrolling the remains of Halo in debris-strewn space.

Ahead lies a dangerous voyage home, through a gauntlet of Covenant forces. For the sake of all, the Master Chief and his war-torn squad must not only survive, but take the fight to the enemy with a decisive first strike.

Halo: Ghosts of Onyx (Halo #4)

Continuing the saga of the award-winning Xbox™ game!

The Spartan-II program has gone public. Tales of super-soldiers fending off thousands of Covenant attacks have become the stuff of legend.

But just how many Spartans are left?

While the Master Chief defends a besieged Earth, and the myriad factions of the Covenant continue their crusade to eliminate humanity, an ultrasecret cell of the Office of Naval Intelligence known as "Section Three" devises a plan to buy the UNSC vital time. They're going to need hundreds of willing soldiers, though . . . and one more Spartan to get the job done.

The planet Onyx is virtually abandoned and the perfect place to set this new plan in motion. But when the Master Chief destroys Halo, something is triggered deep within Onyx: Ancient Forerunner technology stirs, and fleets of UNSC and Covenant race to claim it to change the course of the Human-Covenant War.

But this reawakened and ancient force may have plans of its own  . . .
