Parallax

On an otherwise ordinary day in the coastal town of Werrinup, Ben discovers in quick succession that there is a portal to a parallel universe in an old drain, he has a sister, his mother is a Guardian of the Parallax, his best friend has a sneak thief double from another world and these large flying purple insect things (Welkin) want to bite him.

Together, Ben and Katherine just manage to fight off a welkin attack, though Ben has yet to master the Stave which he's 'borrowed' from Veronica. They both want answers to their mother's role as Guardian and the mysteries of their separate worlds, but when Katherine confronts Veronica, her mother is evasive. In Katherine's World, Ben stops repossession of Katherine's home by smuggling in a valuable heritage artefact.

Ben follows Francis (thief) into the third parallel universe where hippies and tie-dye are the rage. There they work out an arrangement. He and the two Francises work out a scam to pay back Ben's Martin. Veronica works with Katherine and her friend Melinda to recover the Stave.

Ben organises a rock'n'roll dance. Katherine brings Stefan, hoping to reunite him with Veronica. The night is a success thanks to Francis (thief).

Katherine's Melinda goes exploring in Ben's world. Melinda and Florence the Chicken find a new portal that leads to a Hi-Tech rubbish tip. The kids arrive to rescue her and are attacked by Welkin and Ben is bitten.

Katherine and Ben play an inter-world version of pass the parcel as they each try to off-load Francis (thief's) loot from the futuristic rubbish tip. They are almost caught and their inter-Parallax travels exposed, but Veronica saves the day. Francis (thief) discovers theTechno Town version of Werrinup and Una, the girl of his dreams.
