Sea's Turn is Book 2 of SeaScape. Sea, Val and Gloria return to civilization with their children and survivors of the mutiny. CSIC, instead of honoring payment, forces a mission on them. Val must investigate a fleet of alien ships and determine their worth. A Warder has them check two colony worlds fallen silent. They'd thought they were done with Azkor, instead their changes have become a curse.
