Who do you trust when your soul is on the line?

Kellen and Reichis have just finished fighting a duel in the mountains when Kellen inadvertently smears blood on the Daroman flag – an act of treason for which the Marshals have no choice but to arrest him. Just before he’s put before the Queen to be executed, Kellen is given a strange piece of advice from one of his fellow prisoners: kill the Queen and he’ll be given clemency by those who take power. But when Kellen comes face-to-face with the eleven year-old monarch, he realises she’s vastly smarter than he expected – and in a great deal more danger.
