#49 The Identicals by Elin Hilderbrand

Quote
Nantucket is only two and a half hours away from Martha's Vineyard by ferry. But the two islands might as well be worlds apart for a set of identical twin sisters who have been at odds for years. When a family crisis forces them to band together — or at least appear to — the twins slowly come to realize that the special bond that they share is more important than the sibling rivalry that's driven them apart for the better part of their lives.

Definitely a light and fluffy beach read.
