In the concluding book of the "Golden Queen" trilogy, the insectoid Dronons have lost their queen, and their invasion has ground to a halt. Unable to deviate from natural law, the invaders cannot continue their conquest of the galaxy until a Dronon is once again the Golden Queen. To do that, they must defeat Maggie Flynn, the beautiful orphan who now reigns.
Only an ancient system of transport gates has kept Maggie and her companions, the human bounty hunter Gallen O'Day and the sentient bear Orick, one step ahead of the Dronons. But now, out of worlds and out of hope, they are stranded on a planet called Ruin, far beyond the gates and off the star charts. The desolate rock and its hundred inhabitants are ruled by the ancient eccentric, Lord Felph, who has spent 600 years searching for a mythic relic. Maggie, Gallen, and Orick must risk their lives to find this relic, for without it nothing will stop the Seventh Swarm.
