Siege and storm (Libro en inglés)
The Darkling is more determined than ever to claim Alina’s magic and use it to take the Ravkan throne. With nowhere else to turn, Alina enlists the help of an infamous privateer and sets out to lead the Grisha army. But as the truth of Alina’s destiny unfolds, she slips deeper into the Darkling’s deadly game of forbidden magic, and further away from her humanity. To save her country, Alina will have to choose between her power and the love she thought would always be her shelter. No victory can come without sacrifice–and only she can face the oncoming storm.
