Jealousy is a big issue in my book Peace, Love & Baby Ducks by Lauren Myracle. The jealousy is mostly between the two main characters, Carly and Anna. Two different sisters, different personalities and different styles but jealousy has brought them to fight.
      Carly is the oldest in the family, after going to a summer activity outside of the country she came back to a shocking surprise. Anna. She changed from being the sweet & adorable little Anna, to the new whoa Anna.
Coming home and seeing your little sister drastically change physically and mentally can be pretty intense.
 "During the six weeks I was gone, she went from being 'cute little Anna' to the kind of girl guys drool over, and I don't know whether to be jealous or not. Well, no. I am jealous, but I don't want to be. She's my little sister. I love her." Carly she didn't change much, maybe mentally but not physically. Having your little sister "hotter" than you, you will probably get jealous. Carly was also in the situation where many people would get her jealous of Anna because they would rub it in her face that she's prettier and etc, especially Carly's best friend Peyton.
     Even though sometimes jealousy makes Carly and Anna fight they always find a way to forgive each other for whatever the reason they were mad for was. When Carly's bestfriend comes in the story something change. Peyton was always on Carly's side for everything. Until the day she started hanging otu with Anna. Carly was worried that Peyton would leave her for her younger sister.     It was hard to find who Anna truly was. At many times in the book I found myself pretty confused when Anna was talking, whether it's the fact that Carly is different than she remembered or it was just Anna's hormones. Throughout the book I noticed that Carly isn't the only one that gets jealous in the family, Anna does too. Ever since Carly came back from the summer activity she went to. Anna has been jealous. Anna is jealous of her personality, the sweet girl Carly is and the fact that Carly doesn't care what anybody says, this really inspires Anna. But, it's hard to not care what people say when you have a body like Anna's that everybody is always talking about.
     Jealousy can be a tough thing to deal with, I would know because I am a pretty jealous person myself and I have a similar situation with my sisters. Friends can also make you jealous whether its looks, personality or just the way they are. but don;t ever let jealousy break up a important relationship.
