Halo: The Ferrets Books in Order

Special Inspector Veta Lopis investigates a serial killer who may be concealed among the Spartans on Gao. Her case collides with a fight over ancient Forerunner technology, as Insurrectionists and a hostile Covenant remnant threaten to turn the planet’s secrets into crisis.

Following the assassination of Fleet Admiral Graselyn Tuwa and the kidnapping of her family, ONI sends new operative Veta Lopis and a team of Spartan-IIIs to find the culprit. Supported by Blue Team, they uncover a more dangerous plot involving a Covenant splinter faction and Argent Moon.

On the Ark, the Keepers of the One Freedom intend to activate Halo and complete their Great Journey. Embedded among them, ONI operative Veta Lopis and the Spartan-IIIs known as the Ferrets must stop the group before its plan becomes a galaxy-wide catastrophe.
