Dragon's of the Valley is the first truly Christian fantasy fiction novel that I've read and I can honestly say I enjoyed it. It's central theme based around the usual "good guy vs. bad guy" model with the peaceful and enlightened town of Chiril suffering an unprovoked attack by the brutish, violent, and somewhat dimwitted kingdom to the South.
The character The Grawl provides an interesting side plot portraying a skilled hunter/assassin with a tragic history that makes you feel a little sorry for him despite the fact that he is a cold-blooded killer. His apathy and arrogance really add depth to his character and in the end he personifies the idea that sometimes evil isn't always black and white.
Along with the drama of love and death, fear and excitment there is also plenty of comic relief provided by the perpetually confused but always affable Lady Peg. Her barely coherent ramblings never failed to provide a smile and sometimes even a chuckle or two.
Adult readers, however, may prefer something with a bit more depth and the Wulder references seemed to me to be a bit forced at times doing slight damage to the overall flow of the story but all in all I think it is a great book for older kids and teenagers. It's clean, engaging enough, not too violent, no real objectionable material and therefore I think it is definately a book most parents could feel comfortable giving to their children.
