Nadya Skylung paid a high price when she defeated the pirates on the cloudship Remora: She lost her leg. But has she lost her nerve too? When Nadya and the rest of the crew of the cloudship Orion reach the port of Far Agondy, they have a lot to do, including a visit to Machinist Gossner's workshop to have a prosthetic made for Nadya. But though the pirates are far away across the Cloud Sea, Nadya and her friends are still not safe. A gang leader called Silvermask is kidnapping skylung and cloudling children in Far Agondy. When Nadya's friend Aaron is abducted, Nayda will stop at nothing to save him and the other missing kids, and put a stop to Silvermask once and for all.
