They have also added a blurb to their online catalogue listing for the next Typhon Pact book, and part one of David R. George III's new duology, Plagues of Night:
The final novel in the acclaimed Vanguard saga, based on Star Trek: The Original Series!
Secret operations, sealed orders, high-risk military special operations—such dangerous missions have been at the core of the Star Trek Vanguard series since its inception. Four great nations—the Federation, the Klingon Empire, the Tholian Assembly, and the Romulan Star Empire—have all taken tremendous risks in their race to learn and control the technologies of the ancient interstellar hegemons known as the Shedai. Now get ready for the mystery of the Taurus Reach to be revealed….
In the wake of the final Borg invasion, which destroyed entire worlds, cost the lives of sixty-three billion people, and struck a crippling blow to Starfleet, six nations adversarial to the United Federation of Planets—the Romulan Star Empire, the Breen Confederacy, the Tholian Assembly, the Gorn Hegemony, the Tzenkethi Coalition, and the Holy Order of the Kinshaya—joined ranks to form the Typhon Pact. For almost three years, the Federation and the Klingon Empire, allied under the Khitomer Accords, have contended with the nascent coalition on a predominantly cold-war footing. But as Starfleet rebuilds itself, factions within the Typhon Pact grow restive, concerned about their own inability to develop a quantum slipstream drive to match that of the Federation. Will leaders such as UFP President Bacco and RSE Praetor Kamemor bring about a lasting peace across the Alpha and Beta Quadrants, or will the cold war between the two alliances deepen, and perhaps even lead to an all-out shooting war?
