Emily and Chess are lifelong friends who decide to spend a summer at a villa in Italy. The trials of adult life have caused them to drift apart, so they are looking forward to reconnecting.
This is the same villa where in 1974 a group of five people spend the summer at the same villa and one of them ends up dead. Out of this group, one was already a rock star. One records a best-selling album, another writes a book (suspiciously about a murder in a villa), and the other is convicted of the murder. These aren't spoilers, as this information is given fairly early. Part of the narrative is also passages from the book that was written during the summer of 1974 (which involves more characters!)
Emily, an author, gets interested in the history of the villa and begins to research what happened. Chess is also a self-help author and begins to press Emily to let her help write a book about it. Emily doesn't want Chess's help, tensions build, and things go south from there.
So it takes a while to sort it all. There are a lot of characters and two time periods. Hawkins is a good writer, so it all makes sense, but I thought it all went on a bit too long. I had read about the "twists," and was looking forward to them. But it takes about 80% of the book before anything twisty begins to happen.
Don't get me wrong--there are more twists than you realize. I suspected something of the sort...for a while, but it kept going farther than I ever imagined.
I would recommend The Villa. The characters are interesting, even if the buildup goes on a bit too long. (and I just realized this book is less than 300 pages. Seemed longer...) The twists are clever and worth the wait.
