Shadow Curses by Nellie H. Steele

Her woes are getting worse. Will she find her mother, or will she succumb to the deadly magic?

Shrunk to six inches, Paige Turner, along with her teacup dragon partner, Dewey, are still on a desperate mission to find her mother. With a lead on the horizon, she takes her tiny self to the location, hoping to find at least a whisper of her mom.
What she discovers is almost more shocking than the magic she shelves. But her hope is short-lived, and soon, her services are soon required elsewhere. As Paige tracks another deadly artifact, she faces foes like never before–and a new realm frighteningly similar to an old-school video game.

Will Paige be able to shelve the latest magic and continue her search for her mother, or will she hit a dead end…literally?
