"Beware the cyborg!"

Breathing his last breath, Billy Bones gives Jim Hawkins an omnious warning and a strange holographic map. Jim quickly realizes that the map leads to Treasure Planet and the "loot of a thousand worlds." Soon, Jim is working in the galley of a solar galleon, the RLS Legacy, bound for the long-lost planet. Despite Bones's warning, Jim becomes friends with the ship's cook, a cyborg named John Silver.

But can the cyborg be trusted? Or is he on a secret quest of his own? Jim's life and a galaxy of riches depend on the answer!
