Adrian Vale has spent three books surviving—erased past, forbidden mark, a bond he never agreed to. Now he finally knows the truth: who took his memory, why he was placed in the Nursery, and what the mate bond file signed six years ago actually means. Knowing it might get him killed. The Imperial Council wants him neutralized. Chancellor Banks wants him used. Headmaster Sable wants him as leverage. And Lucian—the Emperor who marked him, who locked down the Nursery, who has spent two books closing every exit—wants something none of them have words for. Lucian can crush the Council and hold the Empire. But Adrian won't be held. Not anymore. If Lucian tightens his grip, he becomes every threat Adrian ever survived. If he lets go, he risks losing the one thing six years of sovereignty couldn't find. Dio is watching. The hatchlings are waiting. And somewhere in Annex Twelve, the last piece of Adrian's past is about to make the choice for both of them.
