Book Covers: That One Doesn't Match

 OK, do I read this book recently that I really enjoyed.   HOWEVER, the book nor the title match the content inside the book.  I loved both the cover and the title, but when I realized what the book was exactly about, it was jarring for me.  I had to take the cover out of the equation.  The lovely cover to me says this is a book on the seaside with a library or little free library. It's women's fiction.  And it's a little bit right. The story does take place on an island (think Nantucket or Martha's Vineyard). There is a character that works in a library.  BUT: It's really about an unsolved murder, a trio of friends who lied about the timeline, and a body that appears 20 years later, reopening the case.  Again, it's a good story. And I've read several of the authors previous books and enjoyed them. I just couldn't get past the cover. So, I made my own and changed the name of the book:  It's not perfect, but it's no longer light and happy. There's a little bit of darkness to it. And there's a lighthouse, which is a key point to the story.  Sadly, the library doesn't factor much in the book. There are a couple scenes in the library.  Is this just a bookish quirk of mine? Or does it bug you too?
