Just hours following their climactic battle on the Forerunner planet Genesis, the Spartans of Blue Team and Fireteam Osiris find themselves running for their lives from the malevolent machinations of the now-renegade artificial intelligence Cortana. But even as they attempt to stay one step ahead, trouble seems to find Spartan Edward Buck no matter where he turns.

The military-grade artificial intelligence known as Iona has only one week to live. After that the UNSC will legally terminate her seven-year existence in order to stave off the threat of the data corruption phenomenon known as "rampancy", a condition that will eventually take hold of her functionality and persona, endangering all those around her. In a last-ditch effort to save herself, Iona has successfully launched an unprecedented legal appeal against her own death sentence.

Broken Circle will explore an Elite splinter group rebelling against the Covenant in its earliest days, a brave Prophet caught in the machinations of the new Covenant leadership, and the root of the betrayal that would ultimately shatter the Covenant during events seen in the blockbuster Xbox video game Halo 2.

It's 2535. It is the first, desperate days of the Human-Covenant War, and the United Nations Space Command has enacted “the Cole Protocol” to safeguard Earth and its inner colonies from discovery by its merciless alien foe. Many are called upon to rid the galaxy of lingering navigation data that could potentially reveal the location of Earth and ensure the destruction of humanity.
