Hey Javs! Welcome!
Yes, the GFL books are a series, and they work in order. It's not *strictly* necessary for you to read the other books before THE MVP, but you'll get a WHOLE LOT MORE out of THE MVP if you know the other books.
All of them follow the life and times of Quentin Barnes and the Ionath Krakens, and in order they are: THE ROOKIE, THE STARTER, THE ALL-PRO, and coming this September, THE MVP.
There are three more books in the series that come after THE MVP, and we're currently just calling them GFL #5, GFL #6, and GFL #7.
Hope that helps.
