Vampire Novels Making a Comeback

Some of you may have noticed that vampire novels are back on the rise. We've had a few books to prove that such as The Beautiful by Renee Adieh and Blood Countess by Lana Lopovic. It has been over ten years since the release of Twilight. Twilight was the highlight of vampire novels that brought light to others such as Vampire Diaries. Other vampire based books released during this time such as Vampire Academy, House of Night, Morganville Vampires, and so many others. Right now there isn't that many, but if one of these novels becomes popular enough they will be making a comeback. This could be good and bad for the book community. Some creators really care about cashing in on good story topics when they can. Some of these ideas are successful, while with others you can tell they are just cash cows. Also, authors who already created a vampire series may "surprise" you with another book to the series. Or if the book contained a loved enough side character they can make another series featuring this character! Boom. Other authors may have been wanting to write a vampire novel and perhaps it was never the right moment. It could be lack of inspiration or the pulication company probably told them no. If the novels become big enough again the publisher will give them the green light to make this vampire story happen. I'm honestly hoping for mermaids to finally get a push in the mythical creatures area. I love vampires, but I feel like vampires and werewolves already had their shot multiple times throughout history. Can another creature like a mermaid or even a fairy get a chance? I hope a novel about mermaids eventually becomes even bigger than vampire novels and I'm sure it will happen one day. Just my thoughts on vampires very possibly making another highlight in the book community.
