Ulysses Moore books how many other sequels are there and what's their titles?

Answer 1

Wikipedia has a total of 8 books listed so far:

http://it.wikipedia.org/wiki/Pierdomenico_Baccalario.

But not all of them have been translated yet

If you can't read Italian, here's the list of books yet to be translated:

* The Door to Time

* The Long-Lost Map

* The House of Mirrors

* The Isle of Masks

* The Guardians of Stone

* The First Key

* The Hidden City

* The Master of Lightning

* The Shadow Labyrinth

It may be a while because it takes several years before they are translated. We should see the Guardians of Stone pretty soon cause it was only about a year after The Isle of Masks. I can't wait!
