Query: Bad characters

The characters are all woefully underdeveloped, even the hero of the book. The action scenes are passable, but the plot is sloppy. Who decided to publish this amateurish attempt? Here's hoping the author gets better as the books continue. Not that I will be reading them (to my kid). Even for children, life's too short to read bad books; there are too many better ones to switch to.
