The long journey of the Neptune is well underway. Lady Vivian is counting on her associate Long John Silver to take control of the expedition. But Silver doesn’t have enough men to take over the ship, and Captain Hastings doesn’t trust him. In the close quarters of a tall ship, tensions rise; betrayal looms… Blood will be spilled before the vessel reaches the Amazon, and a single act of routine brutality will throw the Neptune into a maelstrom of death.
