Star Trek: Legacies Book 3: Purgatory’s Key by Dayton Ward and Kevin Dilmore
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, from Christopher Pike to James T. Kirk, has guarded this secret with his life.
Now, Romulan agents have succeeded in stealing the device and using it to banish Ambassador Sarek and Councillor Gorkon to an unknown realm in the midst of their groundbreaking Federation-Klingon peace negotiations. With time running out as interstellar war looms in one universe—and alien forces marshal in another—will Captain Kirk and his crew preserve the tenuous peace and reclaim the key between the dimensions?
Purgatory’s Key is the final installment in the Legacies trilogy. We get to see more interaction on the planet from the alternate universe, but it’s still quite a bit of a mystery. With the Romulans closing in on the Enterprise and xenophobic, ruthless aliens hunting the individuals stuck in the alternate world – there’s a lot packed into this finale. The strength of this story was the character interactions – from some powerful scenes with Sarek to an upheaval aboard the Romulan ship. I thoroughly enjoyed this trilogy, and the climactic ending did not disappoint. With plenty of intrigue, suspense, and drama – this was a well-paced story from a talented writing team.
