When King Lucius is imprisoned in a magic mirror by an evil wizard, he is forced to watch as his life is destroyed and his kingdom brought to the brink of ruin. Trapped in his own reflection, he only has the freedom to move and talk when the wizard sleeps. With his subjects under the dark spell of the wizard, Lucius is forced to rely on the most unlikely of heroes if he hopes to get his life back. Harry comes from a long line of assassins and prides himself on being one of the best in the kingdom, but when he is hired to kill King Lucius he discovers that all is not as it seems in the Kingdom of Cinders. Harry agrees to help Lucius in return for a full pardon for his crimes, but to complete his quest he may have to give up everything, including his freedom and the king he has come to love.
