In a strong debut, Bardugo draws inspiration from Russian and Slavic myth and culture to kick off her Grisha trilogy. In the nation of Ravka, Alina Starkov is a junior cartographer’s assistant in the army, while her best friend Mal is an expert tracker. When a perilous mission into the magically created Shadow Fold goes wrong, Mal is gravely wounded and Alina manifests the rare ability to summon light. Immediately recruited into the order of the magic-using Grisha, Alina is taken under the wing of its intimidating and powerful leader, the Darkling, and heralded as the potential destroyer of the Shadow Fold. As she navigates Grisha politics and uncovers well-hidden secrets, she realizes that the fate of the nation rests on her shoulders and she may be in grave danger. Filled with lush descriptions, intriguing magic, and plenty of twists, this memorable adventure offers action and intrigue mixed with an undercurrent of romance and danger. Alina’s angst and passivity are a bit of a letdown, but Bardugo’s storytelling and world-building more than compensate. Ages 12–up. Agent: Joanna Stampfel-Volpe, Nancy Coffey Literary Agency. (June)
