# Book Blurb Generator

Craft back-cover book blurb options that hook readers on your premise and stakes without revealing how the story ends

Category: Creative

## Prompt template

```
I need back-cover copy for a book I've written or I'm still drafting, and unlike a synopsis, it should hook a reader without giving away the ending.

Here's my book: [BOOK_SUMMARY] (the premise, the main character, and the central conflict)

The genre is [GENRE:select:fantasy,romance,horror,mystery or thriller,science fiction,literary fiction,young adult].

Comparable titles or authors, if any: [COMP_TITLES?] (books or writers your book might sit next to on a shelf)

The length I need is [LENGTH:select:short - under 100 words,standard back-cover length,extended for an online listing].

Write 2 to 3 blurb versions based on my inputs. Hook the reader on the central question or the stakes without revealing how the story ends. Match the voice and pacing typical of [GENRE], quick and punchy for a thriller, warmer and more character-forward for romance or literary fiction. After the versions, note which one leans more mysterious and which leans more plot-forward, so I can pick based on what the cover art and title are already doing.
```
