Siobhan Dunmoore is now in command of Iolanthe, a massive Q-Ship charged with anti-piracy patrol. While returning for resupply, they find the Naval base on the planet Toboso, and the colonial administration facilities, destroyed by orbital bombardment. Many critical supplies have also been pilfered by the raiders. The crew of the Iolanthe sets off on a complex chase to bring the perpetrators to justice.
I must gripe again that, just as in the previous instalment, there is an out of context jibe at leftist thinking for no plot-related reason.
