When Mallory Westbrook comes home for her great-grandfather's ninetieth birthday, she doesn't realize that Jake Summerford had been invited as well. She's spent the last few months transitioning from an awkward teenage girl to a put-together twenty-year-old woman—all in hopes of Jake noticing her. Now that they'll be together in Magnolia Sound for an entire weekend of celebrations, it's her perfect chance to show the four-years-older Jake that she's not a kid anymore. But will she be able to do that while also dealing with her annoying twin brother, Sam, and her family who wants to keep her a young girl forever?
