Madison Chase’s holiday break is drawing to a close and she’s eager to leave the gray Washington winter and join her Aunt Sid on a warm vacation to Cabo San Lucas, Mexico. Maddie is pleasantly surprised when her good friend Ryan McIntire shows up to enjoy the trip with them, and she looks forward to spending time with him. But when Ryan runs into his high school crush, the beautiful Shelby Wagner, Maddie’s jealousy threatens to spoil their sun-drenched days.

Unsure of her relationship with Ryan, Maddie distracts herself by befriending a local girl, Francesca Tarrago, who is both intelligent and hardworking but lives in deep poverty. As Maddie does what she can to help Francesca, she discovers a secret that Shelby has been keeping from all of them. Can Maddie put aside her conflicted feelings and love Shelby enough to help her?
