Aladdin and the Flying Dutchman:

Aladdin and the Flying Dutchman By: J. R. Rain and Piers Anthony
Fiction: Fantasy, Paranormal, 165 pages
Book Count: 44

This is book 3 in a series based off the question of, what did Aladdin do after the end of his story in Arabian Nights.  As you might have guessed from the title it includes a mixture of different legends, myths and beliefs.  This gets interesting when mixing them all together.  Aladdin is Muslim, but goes to a Hades based off of Greek Mythology (with Greek gods and demi-gods), where they also talk about Purgatory.
At the start of the book, Aladdin is already flying on the Flying Dutchman, with it's ghostly crew.  The story is actually about the key to Hades being taken from the sirens as they were attacked by a kraken.  Aladdin and his friends must stop the key from being used, having many adventures as they try to do so.
