What would you do if you discovered that one choice could change your destiny? Would you take a chance, or would you walk away? When eighteen-year-old Katie O'Reilly unexpectedly receives a watch that once belonged to her late grandfather, she has no idea she has also gained the power to change the destiny of others.

Katie is serving an internship in the behavioral science unit at the hospital, and there she meets Edith Sampson, who is being treated for alcoholism despite her youth, thanks to her dysfunctional family. As the two girls meet, Edith tells Katie she wishes she could have a redo for the events that led her to that point—and the watch grants her wish. Soon Katie learns that she can use the watch to help some people but not others. What's more, the mystery surrounding the watch seems to grow deeper the more she uses it, and only time will tell what the consequences might be.

In this young adult novel, a young woman finds herself in possession of a magic watch that can give some people second chances to correct their mistakes and make new choices.
