Star Trek: Legacies

Hidden aboard the USS Enterprise is a secret that has been passed from captain to captain, from Robert April to Christopher Pike to James T. Kirk. Now the return of the enigmatic woman once known as Number One has brought that secret to light, and Kirk and his crew must risk everything to finish a mission that began with April so many years ago.

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.

Eighteen years ago the Starship Enterprise thwarted an alien invasion from another universe, and Captain Robert April took possession of the interdimensional transfer device that made it possible. Since then each captain of the Enterprise has guarded this secret with his life. Now Romulan agents have succeeded in stealing the device and are using it to banish Ambassador Sarek and Councillor Gorkon to an unknown realm in the midst of their groundbreaking Federation-Klingon peace negotiations.
