Query: An okay book.

I thought The Door in the Wall was a mediocrer book;it lacked description of the characters and places. For an example, the book did not describe what Robin looked like; was his hair black or brown, and so on. I was not able to go "into" the story.I thought the plot was pretty good, but the only way I was able to actually go "into" the story was to look at the pictures, that didn't look so good in black and white.
