This fast-paced virtuoso exercise in world-building is the third novel (after 2007’s Queen of Candesce
) set in Virga, a 5,000-mile wide balloon with a central artificial “sun” and many nations clustered around their own smaller suns. Admiral Chaison Fanning, imprisoned for a daring raid that foiled an attack on his home nation of Slipstream, is rescued by his wife, Venera, but finds he’s now regarded as a traitor. Fighting alongside Antaea Argyre, a mysterious woman from the dark far edges of Virga, Fanning learns more about the universe outside and the powers of Candesce, the central sun. Virga is wonderfully imagined, with itinerant gravity sellers, floating farms in nets of dirt, and battles in which one town invades another as buildings smash together and people gather at windows with homemade weapons. The intrigue surrounding a brewing revolution and the threat of invading forces carry readers quickly through this adventure and on to the next installment. (Aug.)
