How is it that I can crank out twelve 80,000 word novels, but writing a blurb for the back cover of any one of my books brings me to my knees?

I spend DAYS on blurbs when I could be writing thousands of words on my next novel; I agonize over wording those back-of-the-book three paragraphs  in ways I never do on my novels.

The challenge of a blurb is more than summarizing a whole novel in 150 words.  I can manage that task easily.  Instead the problem lies in my lack of understanding of what words compel a buyer to want to read my book.  Readers are smart.  They prefer books that are complex and accessible  but with unique and intriguing plots, spiced with interesting and believable characters.  But how do I convey the intricacies of my plot and the convoluted relationships of my heroine and hero in 150 words without either 1)confusing the reader, or 2) oversimplifying both plot and character?

Heavy sigh goes here.

I’m desperate for the reader to pick up my book and enjoy my story, but grabbing that reader’s interest in twenty seconds with a few words seems an impossible task, no matter how many blurb-writing courses I’ve taken to learn the craft.  So forgive me as I oversimplify plot, character relationships, and themes.  Trust me, the complexity, uniqueness and excitement is in the book despite the spare, banal nature of my blurb.
