Bingtown is a hub of exotic trade and home to a merchant nobility famed for its liveships—rare vessels carved from wizardwood, which ripens magically into sentient awareness. Now the fortunes of one of Bingtown's oldest families rest on the newly awakened liveship Vivacia.

For Althea Vestrit, the ship is her rightful legacy. For Althea's young nephew, wrenched from his religious studies and forced to serve aboard the ship, the Vivacia is a life sentence. But the fate of the ship—and the Vestrits—may ultimately lie in the hands of an outsider: the ruthless buccaneer captain Kennit, who plans to seize power over the Pirate Isles by capturing a liveship and bending it to his will.
