A quirky, twisty scifi/adventure/romcom set in space. Canterbury is one of thousands of ships wandering interstellar space. Life on board is quiet, stable, regimented, stagnant.

Siblings Kendal and Rowan are bright, imaginative and adventurous. Kendal routinely takes "shortcuts" by leaping out of airlocks. Rowan snoops through Canterbury's restricted Archives, looking for ancient conspiracies. In short, they're "troublemakers".

When one of Rowan's wild conspiracy theories turns out to be true, the two (naturally) dive head-first into a cascade of events involving a rogue planet, an unexpected visitor, a malevolent A.I., and the very reason behind Canterbury's existence.

And they have to do all this while dealing with familial obligations, politics, romantic entanglements, not to mention Rowan's coming of age and subsequent gender assignment counseling sessions.
