It's a good sign when I open a package from Tommy Nelson, announce it contents, and one of my children disappears with the book!    This happened with our current review, Fire Prophet. 

When my daughter read Spirit Fighter, she was hoping the next book in the series would come out soon. Her exact words then were:  "Spirit Fighter was just like Percy Jackson, but better!"  

The next book in the Son of Angels series is out, and Anna liked this book every bit as much as the first.
