Vineyard Winds. A Vineyard Sunset Series, #18

Winter winds sweep across Martha's Vineyard. A Montgomery family member goes missing, and the past is never as it seems. Claire's twin daughters have always been thick as thieves. But on the night of New Year's Eve, something shifts between them-and Gail and Abby refuse to speak. When Gail disappears from her college campus shortly thereafter, Claire realizes there's something sinister about the twins' argument-but she's too broken-hearted to understand.
Rina is a private investigator living between Martha's Vineyard and Los Angeles. She's head-over-heels in love with Steve Montgomery, but she isn't sure he feels the same. But Gail's disappearance forces Rina to acknowledge horrific stories from her own past. Thirty years ago, her sister went missing -- and she never learned the truth. Not until now. Rina soon realizes that Gail and her sister's stories aren't so different.
History has a way of repeating itself. But this time, Rina has a chance to make things right, save Gail, and build a powerful foundation with the Montgomery family. She just has to act before it's too late. Dive into the eighteenth book of the Vineyard Sunset Series, in which a vibrant cast of characters live out their dreams on Martha's Vineyard. This is the story of the Sheridan and Montgomery siblings, a heartwarming journey of friendship, loss, and love that will make you crave the next book.
