Bow Down to the New Generation of Princesses!

Hello guys!
 Today I'm reviewing the Tiara Club series which has more than thirty books in it. These books are rather simple and easy to read. They are written by Vivian French.
In a magical world with kingdoms and Fairy Godmothers, princesses are so common that the Princess Academy is set up. This academy is divided into numerous stages, such as the first Tiara Club, Silver Towers, Ruby Mansion, Pearl Palace and Emerald Castle. In the Princess Academy, lots of things happen.
There are magic potions, baby dolphins, horses, the sea and, of course, princesses. In each stage, there are a different set of princesses, which makes  it a little hard to remember all those princess names. At the beginning of each book, a note is written from the princess to the reader, saying that both of them are best friends, but it does not seem that way in the story itself.
If you are a reader older than 9 years old, you will probably not find the books satisfying to yourself, even for a short read. These books are mostly for younger girls who have just started to read chapter books and like princesses because the plots are very simple and won't appeal to older readers.
