This was a fun YA fantasy that was written by a teen! 

Ember is riding in the woods one day and gets stuck in a cave from the rain. She finds a strange pink glowing crystal and when she touches it, she travels to the land of Tieria. This land has magic and it turns out so does Ember!

Ember saves Levi a criminal and learns that there is a rebellion to try and take over the King (who is un-aliving magic wielders). There are many dangers that they face together. It's hard to know who to trust sometimes. 

This was a great, easily bingeable book and that end... Can't wait for more!
