Justa and the victorian rogue

Justa is an ordinary kid, except that he lives in a world of magic and monsters, has warrior parents, and his tutor is a wizard with issues. On his sixth birthday, Justa discovers he has magical talent of his own and starts his training as a mage. While accompanying his parents on a mission against a notorious gang of criminals, Justa joins forces with an orphan girl, a witch from old Salem and a long forgotten Aussie outlaw. In the end he and his family are launched into the greatest adventure imaginable; one to save not one, but two worlds.
