The Dark Prince's Vow: Blood Oath Academy

Every child in the kingdom is tested at seven. The assessor pressed his thumb to Elara Wren's sternum and said, flat as old beer, nothing.

She has been nothing for eighteen years.

Then a royal enforcer dies on her kitchen floor, burned from the inside out, and her hands come away covered in ash that glitters gold.

Nothing does not burn a king's man out of his own coat. Whatever Elara is, the Crown has a word for it, and the word comes with a warrant.

What she gets instead is a summons to Blood Oath Academy, where the realm's most dangerous children are taught what their power costs before they are permitted to spend it. Every promise made inside those walls is written in blood, and the Ink always collects.

Kael Morvane is the prince they whisper about. Cold, exact, and the only person on that mountain who looks at a seamstress's daughter with dirt under her nails and sees something worth bargaining for. He offers her a vow. She has no idea what it will cost either of them.

A cornered girl. A desperate deal with the realm's most dangerous man. Deadly trials, forbidden power, and a bargain neither of them can break.
