Star Trek: Legacies: Best Defense by David Mack
A debt of honor: One brave woman ventures alone into a parallel universe to save her old shipmates, exiled there decades earlier by a mysterious device called the Transfer Key. She soon learns the alternate universe harbors not just an alien invasion force, but a secret that underpins its very existence.
A mission of peace: A long-awaited Klingon-Federation peace conference convenes, led by Ambassador Sarek of Vulcan and Councillor Gorkon of Qo’noS. But both sides have enemies who would prefer the two great powers remain at war—and who will do anything to make certain hate wins the day.
An errand of justice: Captain Kirk and his crew seek the stolen Transfer Key that opens a door between universes, but their hunt is cut short by Ambassador Sarek’s plea for help. The Enterprise crew soon becomes targets in a deadly crossfire—one whose outcome will decide the fate of two universes.
Legacies is a trilogy celebrating Star Trek’s 50th anniversary. Spanning decades and several captains of the early Enterprise, I thoroughly enjoyed the first novel that left off with a major cliffhanger. Sometimes the second book in a trilogy can just turn out to be filler. But thankfully, this installment was action-packed and anything but just filler.
As the crew of the Enterprise tries to reclaim the Transfer Key, they also have to deal with a mystery and stop war from breaking out with the Klingons. Meanwhile, Una tries to rescue her old crew mates from a bizarre alternate universe. Full of suspense, political intrigue, and family drama – I enjoyed this story even more than the first in the trilogy. A lot was packed into this fast-paced story. We get to see Bones interact with his estranged daughter and see Sarek at work. There was so much I loved about the characters and story, that it was nearly impossible to put down. And the finale to this trilogy can’t come soon enough.
