Query: My favorite out of the first three.

I have read the first three books. I love Merlin . The Rennaissance Festival is held in my home town, and I always make it a pointo look at all of the merlin brands, artifacts' ect. This book is the best of them all. When he finds his long lost horse/best friend, Ion, their freindship is immiediate. It is a symbol of freindship for readers of all ages.
