Book 52 of 2026: Echoes of Eternity by David Mack.
⭐️⭐️⭐️⭐️: A worthy release to celebrate Trek’s 60th anniversary. Following a single thread over three encounters in three decades, as the Enterprise and Romulans vie to investigate a mysterious object. The time jumps allow the action to take place on the original Enterprise, the refit, and the Enterprise-A, with the characters being their believable selves at each point in their lives. Nicely done.
(Minor vague spoiler:
Also, a very amusing — if you catch it — nod to another famous SF franchise, with somewhat less friendly aliens than we generally see in the Trek universe. It made me laugh.)
