The Last Gatekeeper: The Half-Key and the Secret of the Ashcrown King

An ash-beast should never reach Greyridge. It reaches Alec Harrow's window the same night his dead grandfather's hidden box opens. Alec is a locksmith's grandson with debts to settle, a house to clear, and no reason to believe old heroic tales have anything to do with him. Then he finds a black box beneath the workshop floor. Inside waits a strange half-key, a burned parchment, and a final warning from the man who raised him: do not give it to the Temple.
Go north. Find the Last Gate. The moment Alec touches the half-key, a mark burns into his hand. Monsters come for him. The Temple wants the relic sealed away. The Compass Guild wants answers. And Alec, who has spent his life opening ordinary locks, is thrown onto a road filled with ruined shrines, forbidden gates, ash-touched beasts, and people who know far more about his grandfather than they should.
The half-key is not meant for opening. It is meant for something far more dangerous. To survive, Alec must travel north with allies he barely trusts, uncover the truth behind the Ashcrown King, and learn why the last gate was hidden from the world. But every step draws the Ashmist closer, and the mark on his hand may be leading him toward the one secret his grandfather died trying to bury. A complete epic fantasy adventure for readers who love ancient relics, dangerous quests, guild politics, monster battles, hidden legacies, and fast-paced fantasy with no romance.
