The last magician in the world is no magician at all.

For centuries, creatures of the nights, demigods, and mortal magicians have existed side-by-side with the ‘normal’ world, practicing their arts in secret. But when a mysterious catastrophe erases most of the magic from the world and kills most of the magic users, twelve year-old Aubrey Arthur—heir to a magical legacy stretching back through recorded history—finds herself orphaned in a mundane world that doesn’t even realize what it’s lost.

With only an unreliable golem and a basement full of inert magical artifacts to help her, Aubrey uses what little magic she has left to pick up the pieces of her life. But she soon learns she isn’t the only magic user who survived the catastrophe. A fairy breaks into her house, a horde of zombies attack her after school… and all of that is just the beginning. When someone she thought was dead arrives on her doorstep, she realizes that hidden somewhere in her house is a source of magic—maybe the last remaining source of magic in the world.

And Aubrey Arthur, a sixth grader with very little in the way of magical training, is the only one left who can keep it safe from the monsters.
