The Story of Spider-Man, a level 2 reading book, is quite the step up from a level 1 reading book, many more multi-syllabic words.  The story is told in basic simple sentences, but the story itself is much more complex and actually tells how Peter Parker became Spider-Man as well as solving a crime.  The illustrations are also more complex to go along with the story.  Those who love Spider-Man will love this book.
