Q-16 and the Eye to All Worlds

Headstrong, tomboyish Annetta Severio and her cynical, sharp-tongued friend Jason Kinsman are two teenagers from Toronto, making the most of their mundane existence. Their world is forever changed when they discover that their fathers were once the protectors of a castle called The Eye to All Worlds located where the fabric of the universe is weakest, creating gateways to other worlds, hidden within the bowels of an underwater base known only as Q-16. Learning of the threat of a warlord bent on conquering the multiverse, Annetta and Jason race to reassemble Annetta's grandfather's army, known as The Four Forces before it is too late.
