The Postcard: Secret Author Series, Book 2 (Unabridged‪)‬

An introvert to the core, Aria Scott spends her days in the shadow of her more popular sister, Sophia Scott. The twins are drastically different, and Aria harbors deep-seated anger with Sophia that began their freshman year of high school and simmered well into senior year. When Aria receives a postcard from a mysterious author named X on her birthday, she finds herself slowly coming out of her shell and learning there is much more to life than hiding in the shadows of the past. With the help of X, Aria goes on a journey that changes her life forever. Along the way she learns things about herself she never knew, makes a few friends in unusual places, and finds a way to leave the past behind her. Aria gains a new appreciation for the world, and it all began with a little postcard.
