I loved this book! I enjoyed Lord's other book and didn't expect to like this one more, but I think I did! Abby is secretly in love with one of her best friends, Leo. The two of them and their other best friend Connie do DNA tests, in hopes that Leo will find some family since he was adopted. To Abby's surprise she finds out she has a full blood sister living less than an hour away when Savannah (Savvy) messages her through the test's app and asks to meet. Savvy knew she was adopted but was told her bio parents didn't stay together. To her surprise, they did and the girls also have three younger brothers. Abby knew nothing about Savvy but it seems like their parents may have known each other before the adoption, so she agrees to go to the same camp as Savvy for a month to get to know her and try to work out what happened with their families. To Abby's further surprise, Leo is working at the same camp, so she has to deal with her feelings along with all the family drama.
