The rivalry between Captain Sam and the ruthless Jacob reaches a deadly peak. Jacob, once an ordinary sailor under Sam's command, now controls two ships, relying on a captured Spanish captain to guide him. His ambition drives him to hunt down Sam and the Eagle, but storms, deception, and his own inexperience threaten to unravel his plans.

Meanwhile, Sam and his allies face dangers on land as well as at sea. Cannibals descend upon Robert, Alfred, Moses, and the rest of the crew, leading to fierce battles with muskets and cutlasses. The Martha becomes a looming threat to the Eagle and her consort, and treachery within Jacob's ranks makes his fragile command even more dangerous.

In this tale of survival, betrayal, and courage, alliances are tested, blood is shed, and the fate of captains and crews alike hangs in the balance. Sam and Jacob is a gripping continuation of The Amazing Adventures of the Dreamer — where every storm hides a new danger, and enemies are closer than they appear.
