One Twin Too Many is the fourth diary in the Two of a Kind Diaries.


Oh no! Mary-Kate and Ashley are assigned a new history project. But Ashley's found a way to make her project fun... she's partners with the boy of her dreams: Pokey Valentine! It's the perfect way to get close to him. The only problem is that Pokey would rather get close to a little someone named Mary-Kate! This makes Ashley furious that Pokey is spending time with her sister instead of her, but it just grosses Mary-Kate out that Pokey would rather spend time with her when she'd rather be out playing basketball.
