From her outlandish outfits and bizarre behaviour to her claim 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…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
