So, you have a favorite author that you read religiously. You have them on auto-buy so that you don't miss any of their new releases. You love, love love them! Then after a while you begin to notice a change in how you feel about that author. You don't look forward to their new releases as much as you used to. Their writing has changed and all of the sudden in stead of writing the Historical Romances that you've come to expect and crave, they're writing something all together different, in a genre you don't particularly like.
It happens to all of us at some time. Recently I fell into that category where my favorite author disappointed me by changing her genre. Suddenly her books didn't satisfy my craving. I think it had a lot to do with the fact that her book covers still reflected the old genre, which made me continue to purchase her books, but the story didn't deliver what the cover implied.
It took me a while to figure that out. When you find an author you really like who writes in the genre you love, and then they stop, it's hard to adapt. Readers want what they want. As a writer though, I've come to understand and accept that writer's switch it up to keep it fresh, and to invite in a different crowd.
Writer's are constantly evolving. My very first book, Kiss Me!, which started out as Cupid's Arrow with a publisher, was classified as a sweet romance. The one and only sex scene was at the very end of the book. However, there was a lot of build-up to that event. It might be a little hotter now but it could still be classified as a sweet romance.
Through the years I've gone from sweet, to spicy, to erotic hot. Switched from contemporary, to paranormal, to interracial, to biker suspense. What most readers might not realize is that authors go with what their characters want, they don't follow a formula to suit the writer.
