Hilderbrand's latest summer offering, The Identicals, is once again set in Nantucket (as well as Martha's Vineyard) and centers around identical twin sisters, Harper and Tabitha Frost. With their parents's divorce, the 17-year-old girls are being torn apart and forced to pick a parent to live with and do so by the game, rock, paper, scissors. So off to Martha's Vineyard goes Harper happily to live with her laid-back dad while Tabitha resentfully goes to live with her mother in Nantucket. Both islands have a unique vibe which is the perfect vehicle to showcase the sister's personality differences.With all the family drama, secrets, lies and resentment, the once close sisters have not spoken in more than a decade. Now almost forty years old, the estranged sisters appear to be still stuck in their lives, and their father's death proves to be the impetus for the change that the sisters desperately need to find their way back to each other.
