Bardugo Leigh Shadow and Bone

Soldier. Summoner. Saint. Orphaned and expendable, Alina Starkov is a soldier who knows she may not survive her first trek across the Shadow Fold — a swath of unnatural darkness crawling with monsters. But when her regiment is attacked, Alina unleashes dormant magic not even she knew she possessed.
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.
Welcome to Ravka… a world of science and superstition where nothing is what it seems.
