Book ~ "Why Can't I Be You" (2013) Allie Larkin

From Goodreads ~ When Jenny Shaw hears someone shout “Jessie!” across a hotel lobby, she impulsively answers. All her life, Jenny has toed the line but something propels her to seize the opportunity to become Jessie Morgan, a woman to whom she bears an uncanny resemblance. 

Lonely in her own life, Jenny is embraced by Jessie’s warm circle of friends - and finds unexpected romance. But when she delves into Jessie’s past, Jenny discovers a secret that spurs her to take another leap into the unknown.

Jenny works in PR and is excited about heading off to a work conference. When her boyfriend drops her off at the airport, he breaks up with her, shattering her plans for their future. When she gets to her hotel in Seattle, Myra, who is there attending a high school reunion, mistakes her for her friend, Jessie, who she hasn't seen since high school. Given her state of mind, Jenny impulsively goes with it. 

As she gets to meet the others in Myra (and Jessie's) circle of high school friends, Jenny keeps meaning to tell them she's not Jessie. But she didn't have a happy childhood or have many friends growing up so is relishing this experience of belonging and rationalizes that it's temporary. As she gets to know them better, it becomes even harder to tell them the truth.

This sounded like an interesting premise for a story and it was. I was wondering how/if Jenny was going to be able to pull it off and for how long. She had the benefit of Jessie mysteriously disappearing 13 years ago with no contact with anyone. I liked the writing style. It's written in first person perspective in Jenny's voice. As a head's up, there is swearing.
