My rating: 4 of 5 stars
I really wanted to read this book since I loved Tweet Cute. And I'm glad I did (although to be honest I liked Tweet Cute a scant better) There is some romance in it because, well, YA. But the real crux of the book is about an extra credit assignment to swab the cheek and find out your DNA. And wham- the main character finds out she has a sister (full blooded sister) two years older than she is. The two get together without the parents' knowledge and scheme to go to camp together. There are some of the Parent Trap hijinks, but the real story lies behind the pranks. There are fantastic points about an addiction to social media, the pressures of good grades, and what makes a good friend (and recently discovered sister).
