Lila and Robert had three daughters together, Emma, Quinn and Mattie before their bitter divorce. Years later Lila married Adam and had a son named Ray. Around the same time Robert married Evie and together they had a daughter named Sasha. This book tells the story of a beach house in Wainscott, South Fork of Long Island, split between two families, each refusing to give it up. Ray and Sasha are not related, but share three half sisters, the same room in the beach house and many other things throughout their entire lives, but they have never met.

Ray and Sasha feel a connection to each other, which through the years grows into a bit of an obsession. As children they would share the same toys and books each would leave behind at the beach house. Similar to having an imaginary friend, they filled in the gaps and imagined what the other was like. One night they meet briefly and their curiosity grows.

This contemporary was written by the same author who penned the Sisterhood of the Traveling Pants series. I personally have never read the series, but I did enjoy the movie. I am not familiar with her writing style so I'm not sure if this book is written in a similar manner as the Sisterhood series, but I did find this style of writing a bit confusing. There were so many characters and view points to keep track of that I found myself flipping back to the chart, the author graciously provides us in the beginning of the book, quite often to remind myself of who was who.

Both families are eventually forced to come together and family secrets are revealed. I enjoyed the story line of Mattie, the youngest of the three sisters the most.  I wasn't a big fan of Ray and Sasha's romance and found myself far more interested in the reasons behind the bitterness and hostility of the parents and their backstories instead. 

If the premise sounds interesting to you, and you don't mind keeping track of multiple POVs, this would make a good, quick summer beach read. 

I received a free ARC of this book at Yallfest.
