Query: Keaen - A fast moving fantasy adventure.

Keaen is a well-written, fast-paced fantasy adventure mixed with a dash of romance. Like all good fiction books it has characters we end up loving, and those we love to hate. The storyline has nice twists and turns and is never boring. I would recommend this book to anyone who likes fantasy adventure stories.
