That was made me think. Not many of the books I've read over the last 60 years had that in the title. I've read many romances, written romances, but usually they didn't have love in the title.
My wife on the other hand went through a phase of reading Janet Oke. Most of her books used the word. Back in the day when we would gather up books we finished reading and take them to Don't Paperback Book Exchange. Still in business btw, but the daughter is running it now. Anyway, we'd trade in a sack full of books and walk out with five or six books for less than a dollar. Wife didn't like my Sci-Fi books, but as an avid reader when I was done with my books I also read hers. You can now get eight of those books in a collection.
Between marriages as I was floundering I read a lot of Mickey Spillane, Harold Robbins and even Jaqueline Suzanne. Guess what? She had a book with love in the title. They even made it into a movie. Absolutely dreadful, the movie anyway. The only good thing to come from that movie was a song that launched the career of Barry Manilow called Mandy.
I blogged with a guy years ago that was an absolute freak about Steve McQueen. Every year he had a McQueen special where he did a blow by blow review of every one of his movies and he interviewed anyone who was involved in the movies letting them tell stories of working with the great actor. One of those interviews was a co-star in Junior Bonner. Low and behold Barara Leigh wrote a book about McQueen and others, which has the word love in it. It's now on my TBR list.
