Ship of Destiny (Liveship Traders, #3) by Robin Hobb

The triumphant conclusion to the magnificent Liveship Traders series.

The dragon, Tintaglia, released from her wizardwood coffin, flies high over the Rain Wild River. Below her, Reyn and Selden have been left to drown, while Malta and the Satrap attempt to navigate the acid flow of the river in a decomposing boat.

Althea and Brashen are sailing the liveship Paragon into pirate waters in a last-ditch attempt to rescue the Vestrit family liveship, Vivacia, who was stolen by the pirate king, Kennit; but there is mutiny brewing amongst their ragtag crew, and in the mind of the mad ship itself.

And all the while the waters around the Vivacia are seething with giant serpents, following the liveship as she sails to her destiny . . .
