The Secrets of Drak

The fourth in my Kate's Quest series is The Secrets of Drak.
   In The Secrets of Drak, Jode's brother Sam has turned good, and is trying to explain what is happening to Annaliar, for he is getting bigger and stronger quickly.  Sam doesn't know how to explain it completely, so Jode and Sam travel to Drak to find out what is happening to Annaliar, and how to stop him, if they can.  It is a risk of life, and if Jode hadn't gotten her bravery, she wouldn't have had the guts to do it.
