Having saved her new home from Don Thomas Tucker, Enya has earned a place on the crew of thieves she gathered for the heist and is eager to secure it. So, when offered a chance to join them for another job, she agrees without a second thought. This time, however, they'll be stealing something a bit bigger than a vault full of treasure. This time they plan to steal an entire island.

Of course, stealing an island is anything but simple. Especially when the person they're trying to rob is Aladdin, Sultan of Diyar.

If Enya and the crew are to have any hope of getting past Aladdin's djinni and prying the island of Balnibar from his grasp, they will have to sail the treacherous Sea of Serpents, battle cunning pirates, and outrun monsters of every shape and size-all for a chance to speak with the one being in the world with greater command over a djinni than their master. But they will have to hurry. For the island of Balnibar is more than just a pretty prize.

Another djinni, one even more powerful than Aladdin's, slumbers somewhere beneath Balnibar's verdant jungle. If Aladdin finds it before Enya and the crew can stop him, he may well have the power to conquer the world.
