The Dude and I checked the book out and it's night and day to last month's book. This book is clearly 4th grade reading level, it's listed as 4.8. It has some complexity regarding scientists and place names, but not relationships. It will build her vocabulary, but not with words like 'depression' and 'divorce.' Instead with a word like 'adamant,' something Miss E already knows how to be. SAT vocabulary words and various activities are listed helpfully in the back of the book.
I did find myself wondering where the heck the school library gets all these self-published books, though. I'm not knocking whether this is good, mind you. I'm just in awe that the library seems to have such a large collection of them. How does one market this stuff to school libraries? It's almost like there's such a dearth of basic material so they will buy anything if it's cheap enough. Get yourself a formula, be a bit clever with the execution, find yourself some school libraries. Voila. Career.
