This book is about the fate of the Forsaken Shores Alliance… signed by 'Umbra'.
When Grace Morrow and Stitcher Jim joined their crews to form The Forsaken Shores Alliance, they travelled to places few pirates had seen. They even reached The Devil's Roar thanks to the Shroudbreaker, but Stitcher Jim was secretly seeking power for his then-master, the Gold Hoarder. He betrayed and killed all of them but Captain Morrow, who survived her poisoning but was trapped in the Roar. A dark tale indeed.
