This movie is based on the book, The Beach House by Mary Alice Monroe. I haven't read the book (yet) but I really enjoyed the movie. The book synopsis has a minor difference in it from the movie but then we know movies are usually different from the books. On that note, check out author John Green's video at the bottom of this post where he sheds a little light on that subject ;-)
Caretta Rutledge thought she’d left her Southern roots and troubled family far behind. But an unusual request from her mother—coming just as her own life is spinning out of control—has Cara heading back to the scenic Lowcountry of her childhood summers. Before long, the rhythms of the island open her heart in wonderful ways as she repairs the family beach house, becomes a bona fide “turtle lady” and renews old acquaintances long thought lost. But it is in reconnecting with her mother that she will learn life’s most precious lessons—true love involves sacrifice, family is forever and the mistakes of the past can be forgiven.
