Tunuftol's Fortress of Light: Tunuftol Book 1 in Bloomington, MN

Krissa Wittek, a protective big sister fighting to survive the foster system, wants nothing more than a place she and her brother can call home. When the voice from her dreams leads her to a hidden key in "Grandma" Athey's attic and the truth of her identity crashes around her, she sets out on a quest through a locked portal to a world she didn't remember - as the Chosen One of Nyssa - to return the Light and save her world.
