The school of good and evil

Hello! How are you? I've had such a productive weekend. My favorite part being I read the second school of good and evil book and I am in love! It officially is my favorite book series now. And while I do have a few complaints like wanting to see more of tedros being smart and evil or a happier ending it has really captured that raw literature in ways I can't describe. The author isn't afraid to get creative in uncomfortable yet realistic ways and a book dedicated to the consequences of the ending of the last one is brilliant it reminds us all happily ever after have consequences and no one will always be satisfied I'm very excited to read the next book of the series. However I must ask does anyone actually know how many book there are? I've seen some say 3 all the way to 8? Thank you for reading
