Chapter 7

In this chapter, Captain Roderick Blaine prepares the warship MacArthur for an unprecedented mission to intercept a massive alien vessel approaching the New Cal system. Blaine reviews official protocols for first contact, assesses the alien ship's enormous light sail propulsion system, and navigates the challenges of command, crew dynamics, and political pressures as the ship refuels and readies for acceleration. The chapter highlights the tension between duty, uncertainty about the alien presence, and the personal stakes involved in this historic encounter.

Chapter 8

In this chapter, the crew of the MacArthur prepares for a high-acceleration intercept course to meet an incoming nonhuman spacecraft using a light-sail propulsion system. The narrative explores the physical and psychological challenges of sustained high gravity, the tactical considerations of intercepting a potentially hostile vessel, and the interpersonal dynamics among the crew, including the inclusion of a civilian anthropologist and a young midshipman. The chapter also delves into the technical aspects of light-sail propulsion and the dangers of approaching close to a star to decelerate.
