Le dragon de glace, Paperback Book, By: Bardugo, Leigh

Chased by the men of the Darkling, and haunted by the memory of the lives she took in the Shadow Fold, Alina struggles to adapt to her new life away from Ravka, despite the presence and love of Evil. No one has to know who the Summoner of Light is ... Yet Alina cannot escape her past and her destiny for long. Quickly flushed out by the Darkling, armed with terrifying new powers, Mal and Alina are held hostage on the ship of a mysterious privateer. The Darkling charges Mal with hunting down a new magical creature: the Ice Dragon. If he found himself in possession of the dragon's powers and those of Alma, then nothing would stop the Darkling from carrying out his terrible plan ... and destroying Ravka.
