Surrounded by enemies, the once-great nation of Ravka has been torn in two by the Shadow Fold, a swath of near impenetrable darkness crawling with monsters who feast on human flesh. Now its fate may rest on the shoulders of one lonely refugee. Alina Starkov has never been good at anything. But when her regiment is attacked on the Fold and her best friend is brutally injured, Alina reveals a dormant power that saves his life -- a power that could be the key to setting her war-ravaged country free. Wrenched from everything she knows, Alina is whisked away to the royal court to be trained as a member of the Grisha, the magical elite led by the mysterious Darkling. Yet nothing in this lavish world is what it seems. With darkness looming and an entire kingdom depending on her untamed power, Alina will have to confront the secrets of the Grisha -- and the secrets of her heart.

Alina Starkov doesn't expect much from life. Orphaned by the Border Wars, the one thing she could rely on was her best friend and fellow refugee, Mal. And lately not even that seems certain. Drafted into the army of their war-torn homeland, they₂re sent on a dangerous mission into the Fold, a swath of unnatural darkness crawling with monsters who feast on human flesh.

"Alina Starkov no espera mucho de la vida. Se quedó huérfana después de la guerra y lo único que tiene en el mundo es a su amigo Mal. A raíz de un ataque que recibe Mal al entrar en La Sombra, una oscuridad antinatural repleta de monstruos que ha aislado el país, Alina revela un poder latente que ni ella misma sabía que tenía. Tras ese episodio, Alina es conducida a la fuerza hasta la corte real para ser entrenada como un miembro de los Grisha, un grupo de magos de élite comandado por un individuo misterioso que se hace llamar El Oscuro."--Goodreads

A prequel to the "Grisha Trilogy" takes the reader into Ravka's mysterious past, when Grisha lived as fugitives and the Darkling took his first steps on the path to power.
