The title of my book is as important as the characters themselves. So the name of the book is as important as the characters themselves. You can choose an important event as I did. In my first, I named my book La Roe’s after the Heroine in which the story was told from her point of view. Secondly, it also describes part of her. La Roe means The Red and her first name Emerald means Green, she consequentially has red hair and green eyes. La Roe’s is also about an entire family in which her children will come to play mainly her daughter, which according to family tradition will be named La Roe also.
So the name of the book is as important as the characters themselves. You can choose an important event As Fay’s Wish in which the mother Fay makes a wish for her daughter. Then in Mystic Inn, it represents the hotel, and Vampires Revenge represents the revenge our heroine will play on the hero. I think the name should give a clue to the reader of something grand about to take place.
So how to name your manuscript? Well as you write it, an important scene, place, person, or thing will stand out and hopefully shout use me. I find that I don’t know the name until that exact moment. It is as hard as naming your Characters themselves, especially if that name represents them.
One thing to remember though is to never force the name, it will come to you, and if you feel the need to name it temporarily then use the heroine’s/hero’s name, or even something such as contemporary romance, fantasy, or even pain in butt book 3 or whatever number it is.
