When a ghost ship is  discovered, its crew presumed dead trying to reach the storm-shrouded island Akinah, Navani Kholin must make sure the island hasn't fallen into enemy hands. Knights Radiants who fly too near find their Stormlight suddenly drained, so the expedition must be by sea.

Shipowner Rysn Ftori lost the use of her legs but gained the companionship of Chiri-Chiri, a Stormlight-ingesting winged larkin. Now Rsyn's pet is ill, and any hope for her recovery can be found only at the ancestral home of the larkin: Akinah. With the help of Lopen, the formerly one-armed Windrunner, Rsyn must sail into the perilous storm from which no one has returned alive. If they cannot uncover the secrets of the hidden island city before the wrath of its ancient guardians falls upon them, the fate of Roshar and the entire Cosmere hangs in the balance.
Hard cover.
