This books are really very thrilling.In this full set Thea and her colleagues go to fur raising adventures. the character i liked the most is violet. she always wear violet things and is Chinese. The five mouselets of these books study at MOUSE FORD ACADEMY.I RECOMMEND YOU TO READ ALL THE BOOKS.JUST TRY THEM

it is a spinoff title of the geronimo stilton series. books included in the set are good. the plot revolves around five mouselings who are studying in mouseford academy. it is a good book and i enjoyed it actually. geronimo stilton fans like me will enjoy it but some people might not. overall it makes up a good read
