Halo: The Thursday War

In the second installment of the Kilo-Five Trilogy by bestselling author Karen Traviss, set in the expanded universe of the Halo video game series, humanity faces a new, high-stakes war in 2553. The Office of Naval Intelligence's Kilo-Five, a black-ops team, embarks on a critical mission to prevent the Sangheili from regrouping, which evolves into a desperate attempt to rescue one of their own amidst a brutal civil war. As colonial terrorism arises on a surviving human world, the stakes escalate with ties to Spartan Naomi-010, while recovered Forerunner technology adds another layer of complexity to the fragile situation.
