Used Book – The Last Breath, Volume 1: The Gift, Fiona McIntosh

Still an adolescent, Wyl Thirsk must assume the role he was destined for since birth: commander-in-chief of Morgravia's armies! This responsibility leads him to the court of Prince Celimus, a sadistic despot. There, an act of kindness towards a witch condemned to the stake will earn Wyl a miraculous gift, as well as the wrath of his lord and master.

Forced to obey him, Wyl is sent North where war threatens, on a suicide mission to the enemy court... with his only weapon a mysterious power whose existence he doesn't even suspect. However, if he doesn't embrace the Last Breath, he will seal his own doom... and that of the country he has sworn to defend.
