Abby signs up for a DNA service and is surprised when she matches to a full unknown sister. Her new sister is also famous on Instagram. They meet but neither can figure out why Savvy, the sister, was given up for adoption. They decide to spend a month at camp and delve into the mystery. Leo, Abby's best friend and secret crush, is the cook's assistant at the camp.I really loved Tweet Cute and this book is fine though the plot is a bit convoluted. There's a lot of miscommunications and odd twists, but it's a sweet story. It's probably meant more for younger readers but I enjoyed it. The characters are realistic and fun, especially the interactions between Abby and Savvy. The adults are confused but doing their best for their children. The relationship between Leo and Abby is also muddled, mirrored by that of Savvy and Micky, but all comes right in the end. A fun and quick read.
