I received an ARC of this book from NetGalley in exchange for my unbiased opinion. 
 Charlotte "Lottie" Maynard still lives with her mother at age 29 in the house where she grew up. She is agoraphobic and rarely leaves the house but has a famous blog about her two (imaginary) children. When her step-brother, Spin, announces he's engaged to his girlfriend of 3 months, Laurel, Lottie and her sister, Sally, search online to find out everything they can about Laurel. They finally get to meet her that summer when Spin and Laurel come to stay at the house for a few weeks. 
 The characters were definitely interesting, but I felt like I kept waiting for something to happen plot-wise. I also felt like the ending was rather abrupt. I would have liked to have known more about Whit and Perry.
