I have read this Young Adult fantasy and enjoyed it. Actually, I listened to this book via audio book. You can see the review I wrote on good reads below...
This book is a wonderful tale about the struggles that teens face today. It's a great teaching tool, particularly about Jews and about Christ and His relationship with us. Spiritual truths are wrapped up in a fun story full of internal and external struggles. It was an enjoyable book with characters you want to hug right off of the page.
The best think about it is that today it is free on the kindle. Click on the link below to get your free copy.
I hope you enjoy it! I did!
