So far I have gotten two boxes (below is my review):
Here's the okay part: These are not the MOST popular books. So far all 4 books that I have gotten have been less than 4.0 on the Goodreads rating, and I had only heard of one of the books before receiving it.
Here are the great parts: They're all hardcover (delivered promptly at the beginning of each month) and with interesting titles that fall under my theme (young adult). I've read 3 of the 4 books I've received and then put them on my classroom shelves. My students love new books and totally pick books by their cover. For this reason, I will continue subscribing! (Really happy with my purchase!)
