No Reprieve (The Ascendant Kingdoms Saga)

Condemned to exile in an arctic prison colony for murdering his sister's attacker, Blaine McFadden has lost everything -- his title, his family and his fiancé. Velant Prison holds the worst of the kingdom's convicts, overseen by brutal guards who are exiles themselves. When a sadistic guard takes things too far, Blaine's insubordination makes him a target of the prison's notorious commander. To survive, Blaine needs to rely on his wits and his fists -- and a few good friends to watch his back.
