The Talisman of Zandria

Ivy Peterson is Less-Than-Ordinary. She's so very Less-than-Ordinary that sometimes she feels invisible. She is also Not Very Brave.
But part of her wishes she could be something More, that something Extraordinary and Completely Unusual would happen. What she forgets about wishes is that they do sometimes come true.
Ivy accidentally falls into Zandria, a magical world that exists just outside her own. And she's trapped there because someone has stolen the Talisman of Zandria, a magical amulet...
