Midnight Lamp — Gwyneth Jones

Recovering from the events of CASTLES MADE OF SAND, the leaders of the Rock-n-Roll Reich travel across the Atlantic. The USA has not suffered from the technological losses which transformed the UK, so the Triumvirate find themselves in a glossy Hollywood where actors are virtual, cars are intelligent, and they aren't worshipped as they are back home. Ax, Sage and Fi are trying to cope with their recent losses, and reflect on where their relationship now stands.

Meanwhile, there are groups of magic users trying to gain power through human sacrifice, threatening the stability of society. When Fiorinda goes missing, the worst is feared...

This is book three in Gwyneth Jones' critically-acclaimed BOLD AS LOVE series.
