My independent reading book is about two sister one named harmony she's the church girl , she's sweet doesn't like conflict and is engaged at 16. Oh this book is set in the future I don't know how many year into the future though. Then there is her sister melody she's not the mean on that I know of yet but she is pregnant. She's got pregnant because in the future there was this virus going around and anyone over the age of 16 is pregnant also they didn't know each other. Harmony wanted to find her birth parents because she knew she was adopted so instead she found her sister, tracked her , called her , and went on her door step it brought them close even though at first melody didn't want to get close to her sister she did.
