Star Trek: Enterprise: Kobayashi Maru, by Michael A. Martin and Andy Mangles
Star Trek: Destiny: Gods of Night, by David Mack, is the first in an all new trilogy.
Gods of Night follows four captains and their crew: Jean-Luc Picard of the USS Enterprise, William Riker of the USS Titan, Ezri Dax of the USS Aventine, and Erika Hernandez of the Columbia NX-02. In the year 2381, the Borg have waged war on the Federation. And this time, their goal is not assimilation but annihilation. Meanwhile, the USS Aventine is investigating a centuries-old mystery – the Columbia NX-02 went missing in 2156 and has been discovered, seemingly abandoned on a remote, uninhabited world.
