Halo: The Thursday War

ONI's Kilo-Five is running a dirty tricks operation against the Sangheili — keeping former Covenant warriors occupied with their own civil war rather than targeting humanity again — when a routine mission becomes a race to extract a teammate from the heart of an alien insurrection. Meanwhile, colonial terrorism resurfaces on a human world, and for one Kilo-Five Spartan, the man behind it is deeply personal. Karen Traviss's twelfth Halo novel is the middle volume of the Kilo-Five trilogy, testing loyalties and revealing costs.

Euan Morton brings his familiar authority to the ensemble, his narration finding the specific emotional register of a team that operates in moral grey zones and is beginning to feel the weight of that. At nearly fifteen hours, The Thursday War is the most action-intensive entry in the trilogy, and Morton handles the operational sequences without losing the quieter character work that makes Kilo-Five more than a standard military unit. Essential reading for fans of the trilogy.
