From the back of the book:
Pirates take whatever they please, whether it be ships, plunder, or people! The adventurers wake to find themselves press-ganged into the crew of the pirate ship Wormwood, the vessel of the nefarious Captain Barnabus Harrigan. They’ll have to learn how to survive as pirates if they’re to have any hope of weathering rough waves, brutal crew members, enemy pirates, ravenous beasts, and worse. But when fortune turns to their favor, it’s up to the new crew to decide whether they’ll remain the pirate’s swabs or seize control and set sail for adventures all their own.
