War of Fire and Fury by Marion Blackwood

The final war against the Iceheart Dynasty has already started, and now it is a race against time to catch up before their enemies can wipe them out completely. But after everything that has been done to her, Selena struggles heavily with the effects of magic. Managing the full impact of it while fighting on the losing side of a war might just prove to be impossible. At least alone.

But her friends are battling their own demons, and not everyone comes out unscathed. With the tension mounting, long-overdue confrontations come to a head in the midst of chaos. Relationships will be changed, loyalties will be tested, and hearts will break, because not everyone survives to see a new era dawn.

For better or worse, the greatest battle of their time will come to an end. But in a war of fire and fury, who will be left when the ashes settle?
