3.5 - Audiobook - I really wanted to love this more because the reviews I read spoke highly of it. Abby took a DNA test & found through there that she was a 100% match to a girl, her sister. We see how their relationship grows, stumbles and grows again. Abby had such a wild summer between learning this family secret, relationship with her best friends changing & a budding romance. This gave me such Parent Trap vibes but for 2021. I needed more Leo & Abby - such a cat and mouse game throughout the book. Still was an enjoyable listen!
