The Harry Potter Series written by J. Rowling and published by Scholastic Press in the U. and Bloomsbury in the U. This series consists of 7 fantastic novels, begining at a low reading level and advancing to an intermediate level.
I'll admit- I've only read the first 2 so far. My husband has been asking me for a while so decided to start reading the series a couple of weeks ago. I am now hooked - SO much better than the movies. I will be done with the rest soon!
