I received an ARC of this book from NetGalley in exchange for my unbiased opinion. 
 Seventeen-year-old Norah suffers from anxiety, OCD, and agoraphobia. As a result, she has been home-schooled for the past four years and only leaves her house for her therapy appointments - even that is traumatic for her. Her only social interactions for the past 4 years have been only her mother, the company that brings food to the house, and following her old classmates' lives on social media. However, when Luke moves in next door, that changes. Luke sees Norah for who she is beyond her mental health problems. As Luke and Norah grow closer, Norah struggles between being glad he's in her life because she really likes him and feeling he deserves better than the relationship she can offer him. 
 Since the author deals with the same problems as her main character, this is a very real look into the life of someone dealing with agoraphobia and OCD. This was a very engaging read, and I found Norah to be a highly relatable character, even to someone who doesn't have the same challenges she does. (However, the odd number of steps thing hit close to home; I am pretty sure staircases with an odd number of steps were created only to make our lives worse.) I loved how Luke was willing to meet Norah where she was and work to understand where she was coming from. The ending felt like a new beginning; I would love to know what happens to Norah over the next year or few years of her life.
