Halo: Mortal Dictata

Halo: Mortal Dictata closes the Kilo-Five Trilogy in April 2553. Staffan Sentzke, a Venezian arms dealer and Insurrectionist whose daughter was abducted decades earlier for the SPARTAN-II program, has acquired a stolen Covenant battlecruiser and intends to make Earth's cities answer for it.

Kilo-Five — Serin Osman, Naomi-010, Evan Phillips, Vasily Beloi and Malcolm Geffen — is sent to stop him, forcing Naomi to confront the father she never knew she had, while the Kig-Yar shipmistress Chol Von pursues the same ship for her own ends. Karen Traviss brings the trilogy's reckoning with ONI's oldest secret to a close.
