Perfect for you if...

You enjoy space opera with genuine stakes and shifting loyalties that force characters into impossible choices.
You like stories where the technology itself becomes a character, especially when it's unreliable or morally complicated.
You want serialised sci-fi that respects continuity but works as its own complete arc within a larger series.

Maybe not for you if...

You prefer standalone novels or self-contained arcs without needing to read book one first.
You're looking for character-driven literary sci-fi rather than plot-driven action and intrigue.
You want slower-paced worldbuilding over propulsive narrative momentum.

About this book

Evan and Anya flee Aethos with a target on their backs, carrying an ancient alien starship. The ship's sentient AI is missing thousands of years of history and is equally unprepared for their escape. As they search for the ship's makers, Evan and Anya uncover an interstellar plot to transform the Commonwealth using alien technology—one far more complex than they anticipated. With two factions competing on Aethos, they must choose a side and determine who can be trusted with the ship's powerful technology. Lost Planet is the second book in the Starship of the Ancients series. It features suspenseful space adventure, science fiction action, alien worlds, and interstellar intrigue.
