Max and Mackenzie: Changes (The Bully Buster Club Book 2)

Life has been full of changes for Max and Kenzie. Max no longer needs to watch over his shy sister, as her confidence begins to grow. And Kenzie is getting comfortable with her changes. New clothes and contacts instead of glasses are the outside ones, but Kenzie's new independence is the biggest change of all. Max is happy for his sister, but when it seems Kenzie might be the target of another bully will her new confidence hold true? And will Max be able to keep his temper and not fall back into being Kenzie's protector, erasing all the new positive changes the twins have fought so hard to make?
