In my book, Auden doesn't like her stepmom just becuase of  her personality; being too perky and cheery all the time. Even though it seems really rude, sometimes I do not like people too just becuase of the way they act. I am pretty sure everyone judges a book by it's cover every once in a while. But the good thing about Auden's experience with her stepmom is that when she stays with her dad and Heidi, her opinion doesn't stay. She soon notices that her dad, the one she thought was a perfect role model, doesn't help out around the house or with his new daughter. Heidi does all of the work, but in general she doesn't complain about it. So I predict that throughout the rest of the book, Auden and Heidi will grow a closer relationship than what Auden expected, and I think that Auden will think of Heidi being less of a stepmom, and more of a friend. But what I am wondering is what will happen to the relationship and Auden and her dad? Will he change for his new wife and his daughter?
