BEAUTY AND THE BEASTKIN

Two hundred years ago, a scorned witch cursed the Ashgrove bloodline to wear the shape of the monsters she believed them to be — until one heir could prove capable of a love freely given. Now Kael Ashgrove is the last of his line, trapped in his beast form on a mountain the crown's maps refuse to acknowledge, and running out of time.

Elara arrives at his castle not by choice but by royal order — sent to "cure" him or face arrest herself, a woman whose own magic has made her as inconvenient to the crown as Kael's curse has made him. She has thirty nights to find a way to break two centuries of grief made monstrous.

She wasn't counting on falling in love with the beast at the end of them.

A slow-burn fated-mates romance of found family, inherited curses, and choosing someone — fully, freely, without an eye on the cost.

Short description (Amazon's 400-character metadata field, some Kobo/D2D short fields):

A scorned witch's curse trapped the Ashgrove heir in a beast's shape two centuries ago. Now Elara has thirty nights to break it — or be arrested for failing. She wasn't counting on falling in love with the monster at the end of them. A slow-burn fated-mates romance of curses, choice, and love given freely.

One-line hook (ad copy, social bios, Amazon's editorial-review-style teaser):

She was sent to cure him. She stayed to love him.
