The universe makes no mistakes… Twelve-year-old Arian never wanted a foster sister, much less the weird and annoying one who has joined his family. From her outlandish outfits and bizarre behaviour to her insistence that the random stick she carries is a magical weapon, Madlock is creeping Arian out. There’s just one thing the pair can agree on: that she’s from another planet. Of course, Arian never meant literally…  It turns out Madlock is the most wanted criminal in the galaxy. Worse still, the only way for Arian to get rid of her is to help prove her innocence. When Madlock summons a portal to another world, Arian is launched into an adventure of intergalactic proportions. For an ancient enemy is stirring in the shadows, and the universe has a bigger plan for them than the pair could ever have imagined.
