Now Alina will enter a lavish world of royalty and intrigue as she trains with the Grisha, her country's magical military elite--and falls under the spell of their notorious leader, the Darkling. He believes Alina can summon a force capable of destroying the Shadow Fold and reuniting their war-ravaged country, but only if she can master her untamed gift. As the threat to the kingdom mounts and Alina unlocks the secrets of her past, she will make a dangerous discovery that could threaten all she loves and the very future of a nation.
