Thirteen-year old Emma's having a really bad day. Nothing at school is going right, and a nasty bully has her sights set on making Emma miserable. To escape her pain, she and her brother run through the forest, where they encounter something they never expected.

When they stumble upon an old tree with a mysterious door, they can't help but travel through. On the other side is a magical land filled with wondrous creatures. But not all of them are friendly, and some are on the attack.

The hunt is on. Will they be able to find their way home, or will their magical journey end in doom?
