For the last year, yacht stewardess Jo Walker has been attempting to complete a bucket list of thirty things she wants to accomplish by her thirtieth birthday. Jo is on track until a family tragedy turns her life upside down, and the list falls by the wayside. But when her two nieces show up unannounced with plans to stay the summer, they discover her list and insist on helping Jo finish it. Though the remaining eight items seem impossible to complete in twelve weeks, Jo takes on the challenge. When she summons the courage to complete item number five—kiss a stranger—and meets Alex Hayes, all bets are off. As her feelings for Alex intensify and Jo's inability to confront difficult emotions about her family complicates her relationships, she must learn to quit playing it safe with her heart before she loses what matters most.
