Not Impressed.  The actual story is okay.  It seems a bit old fashioned, (like something I would have read in the 80’s) and a bit long for the level it states its is.  What is the worst part is all the front matter. There are pages and pages of things that explain the story or ask the reader to pay attention to something.  But this front matter is written at a higher level than the rest of the story.  Then it repeats again in the back matter with more stuff to do or look for, that does not match the reading level of the book.  It has the possibility to frustrate the reader before they actually get to the story.
