When writing a blurb you need to write a very short bit about your book, one that will influence a reader to want to learn more. Doing this in a few words can be very, very hard. You will probably make many trials and tear them up. After writing many, you will find ways to help yourself
What consists a blurb/ You need to show when the story happens, what the problems between the characters are. But don't give up the end of the book. If you do why would the reader want to read your story.
I find this to encompass many trials. Sometimes writing a blurb seems to take longer than the book. What you need to add are words that show the genre. A reader might find your blurb exciting and expect a romance only to find you've written a suspense, mystery or another genre. You need to touch on the main characters and their goals. Giving enough and not too much can be difficult. I've written one blurb that gained a response from the publisher and from readers. Though old, the book is still selling. I'll include it.
Take one doctor who’s made a career of temporary positions and avoiding commitment. Add a nurse who dreams of security and a settled life. Stir in infant twins bequeathed to him by his dead foster sister. Pour them into a small Texas town that wants the doctor to stay. To Dr. Neal McKay, it’s a prescription for a dilemma.
