Query: Disappointing Effort

The Pendragon series involves action, adventure, and a tired derivative formula. O wow here's a brand new territory with problems only Bobby can tackle. don't think you are going to get new information Reader, don't think that at all. after all there are still 3 more books. This formula is getting tiring. Machale seems to not be able to move beyond this or have his characters continue their growth. All the characters have returned to their original cardboard stereotypical traits. Do all the characters have to be opposites?Machale's writing and characters need to grow up though I do admit the man can sure weave a tale!
