You don't know me but I know you

Summary: "There's a box in the back of Audrey's closet that she rarely thinks about. Inside is a letter, seventeen years old, from a mother she's never met, handed to her by the woman she's called Mom her whole life. Being adopted, though, is just one piece in the puzzle of Audrey's life--the picture painstakingly put together by Audrey herself, consisting not only of the greatest family ever but of a snarky, loyal, sometimes infuriating best friend Rose, and a sweet, smart musician boyfriend, Julian. But when Audrey realizes that she's pregnant, she feels something--a tightly sealed box in the closet corners of her heart--crack open, spilling her dormant fears and unanswered questions all over the life she loves. Almost two decades ago, a girl in Audrey's situation made a choice, one that started Audrey's entire story. Now Audrey is paralyzed by her own what-ifs and terrified by the distance she feels growing between her and her best friend Rose. Down every possible path is a different unfamiliar version of her life, and as she weighs the options in her mind, she starts to wonder--what does it even mean to be Audrey Spencer?"-- Adapted from publisher description.
