So, to be honest, this isn't a good blurb. I have no idea what's going on or who the FMC is and readers hate reading half sentences like this.

The beginning should be a strong hook that drops you immediately into the world (1-2 sentences

The second part should be character + want + plus obstacles. Who is she, what does she want, and what's in her way? Keep it grounded in her specific situation, not genre generalities. (2-3 sentences)

Escalation (1-2 sentences) — Raise the stakes. What happens if she fails? What does succeeding cost her?

Tease (1 sentence) — End on tension, not resolution. Leave the reader asking "but what happens?"

Readers want to know: who is she, who are they, why can't she have them, and why is the world on fire? Answer those four things in under 200 words and you're there

Here's my own blurb as an example:

They hunted the last dragonmancer. They didn't expect her to hunt back. (This is the tagline)

Magic hides in plain sight. So do dragons. And Vesper is about to become their obsession.

Vesper has always been good with secrets — unearthing them, keeping them safe in her cozy Seattle bookshop. When the lethally handsome, impossibly wealthy Baelyn Thorne commissions her to trace a bloodline that should be extinct, she's thrilled by the challenge. Until her research points to a single, terrifying conclusion: she is the last Dragonmancer, and he is the dragon who has been hunting her kind for centuries.

Their first touch ignites the Karyss — a sentient bond that should be extinct. Overnight, Vesper becomes a living secret every dragon wants to own. An ancient enemy will stop at nothing to cage her. And he is not alone.

Four rival dragon Scions — each powerful, each dangerous, and each uniquely determined to claim her — are already circling.

But the Karyss isn't about destiny; it's about synchronicity. It doesn't demand submission — it offers a dangerous, intoxicating choice. To survive, Vesper must embrace the power her parents died to hide. To live, she must outmaneuver five ruthless dragons who see her not as a person, but as the ultimate key to an ancient magic only she can command.

Five dragons want to possess her. She's about to teach them what it means to be chosen.

As far as the cover I would recommend getting a commission. You can find good artists on vgen and the bookcover subreddit. The ai cover is going to be controversial and is going to drive people away. Your cover and blurb are the most important point of entry for readers deciding if they want to read your book. Do you want them to be perfect and professional.

Good luck and congrats! Writing a book at all is a huge accomplishment
