An original novella set in the Halo universe—based on the New York Times bestselling video game series!

2560. Over seven years after Covenant forces invaded the planet Criterion, its human survivors are still struggling to rebuild amid mounting resentment toward the Unified Earth Government. When separatists ambush a reconstruction convoy and steal critical equipment, Colonial Administration Authority Marshal Imani Havel uncovers a conspiracy far more dangerous than local rebellion.

With contact from Earth mysteriously silent and Criterion’s defenses stretched thin, Havel’s pursuit leads through abandoned industrial ruins and a vast graveyard of human and Covenant warships orbiting the planet. But as shadowy off-world operatives emerge from the darkness, she realizes the stolen resources are only the beginning—and that an unimaginable threat has already been set in motion.

Outmanned, outgunned, and with no Spartans coming to the rescue, Havel and a battered UNSC assault force must expose the enemy’s true plan before Criterion’s violent past comes crashing down upon its fragile future...
