Vanessa Marshall has spent her life in and out of foster care, with only a vague recollection of the women that left her behind. When she receives a strange letter from her mother three weeks before her 18th birthday, Vanessa knows it’s the only shot she has at finding her real family. The letter instructs her to jump off the Swan Pier into the ocean at midnight under the next full moon. With the steadfast hope that her mother would be waiting for her, Vanessa jumps, only to find that she’s come up for air seventy years in the past.

Journals written by women who took the same time-altering jump help Vanessa realize that the mystery of her mother’s life spans generations and is far more complex than she could have ever dreamed. While living in 1949, Vanessa develops feelings for a boy despite the warnings from previous travelers not to fall in love. As she begins to unravel her mother’s web of secrets, Vanessa discovers that the truth is anything but easy, and the answers are not influenced by past, but have the power to alter her future forever.
