Roseworld - Diane J Cornwell

An unnamed planet, far from the rest of human colonisation, is a haven for space pirates.

Rose McDougal, daughter of the unnamed planet's leader, listens to her father plan an attack on an approaching naval space ship that wants to learn the secrets of a small alien building.

But Rose plans to warn her only friend in the colony, an alien machine, of the impending attack. She hopes the AI will warn the navy before the attack, so she can stop her father's plans.

Roseworld focuses on the unexpected chain of events that establishes a new order, and warns the navy space fleet that the planet is not to be messed with.
