Siege and Storm is a fantasy action book written by Leigh Bardugo, and was first published by Macmillan on June 4, 2013. The book is the second instalment in the Grisha trilogy and was preceded by Shadow and Bone.
The book follows the protagonist, Alina, who is on the run across the True Sea after the events of the previous book. During her life as a wanted person, she must try to adapt to her new surroundings whilst keeping under wraps her true status as the Sun Summoner. Along the way, the Darkling threatens to expose her true nature, having adopted new powers that can destroy the very world Alina is trying to protect.
Kirkus Reviews praised the book for the “Scheming and action carry readers at a breathless pace to an end that may surprise them and will definitely leave them panting for the series' conclusion." New York Times bestselling author of the Divergent series, Veronica Roth, stated that the book was "Set in a fascinating, unique world rich with detail, Shadow and Bone was unlike anything I've ever read.”
