The Archer Princess by E.P. Bali

PRINCESS. HEALER. REBEL

When a dangerous ancient king and his warriors are unexpectedly released from an eternal sleep, one girl is forced into a situation she’s done everything in her power to avoid: marriage.
For her own safety, second-born princess Altara has made a run for it, across the sea to a school for young ladies, deep in the tropical forests of her mother’s native home, the Ellythian Isles.
Keeping her name and title secret she goes undercover to try to live a normal life at the school. But not everything is as it seems and cracks begin to appear in the school’s facade.
Worse, four bloodthirsty warriors have suddenly appeared at her doorstep and are demanding to re-claim their kingdom. Drawn to the self-proclaimed, ruthless King Ashzale Boneweaver, Altara must navigate her own growing powers, forced weddings and the political machinations of the terrifying, alluring magical warriors they call the Old Ones.
