I received an ARC of this book from NetGalley in exchange for my unbiased opinion. 
 Clara and Hailey are conjoined twins in their senior year of high school in the small town they have lived in for almost their entire lives. Clara is into science, especially astronomy, and is the more reserved of the two twins. Hailey loves art, has dyed her hair pink, and dreams of traveling the world. Their parents, especially their mom, have done everything they can to make sure Clara and Hailey are not treated like oddities and have planned for Clara and Hailey to go to Sutter, the small college where both parents teach, after high school. Clara and Hailey have always gone along with this, but on the cusp of adulthood, they are starting to think about their own dreams (dating, art, generally being able to pursue their own lives) and wonder if they can have some or all of it. 
 I really enjoyed this story. The author seems to have done an excellent job of researching what it means to be a conjoined twin, especially of their specific type. The girls had all the same feelings and trials of "normal" teenagers with the added layers caused by the difficulties caused by being conjoined twins. I would love to know what happened in their lives after the novel ended - hopefully the author will write a sequel!
