Description:

Ship of Magic
Wizardwood, the most precious commodity in the world, comes only from the Rain Wilds. But only a liveship can negotiate the perilous waters of the
Rain Wild River, and liveships are hard to come by. They quicken only when three family members from successive generations have died upon their deck.
The liveship Vivacia is about to undergo her quickening:
Althea Vestrit waits for the ship that she loves more than anything in the world to awaken. But her dream of taking her father's place at Vivacia's helm is not to be, for her family have other plans...
And the dark, charming pirate Kennit also lusts after such a ship: he well knows the power of wizardwood and has plans of his own.

The Mad Ship
The Vestrit family's liveship, Vivacia, has been taken by the pirate king, Kennit. Held captive on board, Wintrow Vestrit finds himself competing with Kennit for Vivacia's love as the ship slowly acquires her own bloodlust.
Leagues away, Althea Vestrit has found a new home aboard the liveship Ophelia, but she lives only to reclaim the Vivacia and with her friend, Brashen, she plans a dangerous rescue.
Meanwhile in Bingtown, the fading fortunes of the Vestrit family lead Malta deeper into the magical secrets of the Rain Wild Traders. And just outside Bingtown, Amber dreams of relaunching Paragon, the mad liveship...

Ship of Destiny
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..
