The Forest of the Treelords

From the back of the book: Every year adventures flock to Oakblade to take part in an event that will test their skill and cunning. They must venture into Darklight Forest and defeat the Treelords in combat - only then can they receive the ultimate prize - the Essence of the Wood. But first they must traverse the deadly forest with its traps and foul beasts. This will not be easy - nobody thus far has made it out alive.
