One character that changed is Jenny, she change from very nice to mad and mean to very nice, at the end and the beginning Jenny was lots of fun and always let Esmie try on different things in her room, but then Jenny changed in the middle of the book because Esmie said that her dad was dangerous. Esmie thought Jenny's dad was dangerous because she thought that he killed Jenny's mom. But then she found out that it was someone else. After Esmie apologized for saying something that was not true, Jenny forgave her and she became really nice again. Another character that changed was Lizzie. Lizzie is Esmie's dad's girlfriend, at first she was very afraid to tell Esmie about herself, but at the end Lizzie became fun and was very outgoing. She changed because once Esmie spied on her, and then Lizzie knew that Esmie wanted her to be more like a mom, and not hide a side of her from Esmie.
The main problem of the story is that Esmie's mom died when she was giving birth to Esmie, she tried to help Jenny find her mom, and she trying to get her dad to marry Lizzie, because she really wanted a mom, and when Lizzie was acting weird about where she was going, Esmie went and spied on her. Esmie didn't accomplish her goal of helping Jenny find her mom, Esmie got in contact with Jenny's aunt, but she didn't know where her mom is either, but Jenny was still very happy because she got in contact with her mom's sister. Lizzie didn't marry Esmie's dad yet, but Lizzie is getting closer to their family, and even brought home for them a kitten, so Esmie's whole family is very happy. I would change the part where Esmie spies on Lizzie because I think it very isn't nice to interfere with other peoples life. I think the author's message is, we should not get our hopes up that high, just incase you can't get what you want and will be very disappointed, so we should be very happy for what we have.
