I'm not sure this would be considered a short story but at the same time it is not long enough (for me, I guess) to be a book, anyway..
So, this story follows: Josslyn Tait, a focused, goal-oriented, eagerly looking for love, doctor who has suffered many deceptions and is about to lose hope, Joss lives with her life-long bestie, Amy. Amy's twin sister Kate is the opposite of both Joss and Amy in regards to love, she just wants to live life and have fun, to settle down isn't in her near future.
From the outside you might think that this is a short, romantic story with minimal angst and yes, the premise is accurate but I consider that the response of childhood experience played a huge role in the personality development of one of the main characters which bring so many situations, responses, scenarios that make it way more than a fluffy read but not necessarily robustly good.
