The Emperor’s Guardian

Prince Aiden only wished for anything besides his repetitive and suffocating life in the palace, something that could ignite his long immobilized heart. So when he met a beautiful yet lethal thief, he longs to meet her again.
But when his father is slain, the young prince is forced to sit on the throne and given the impossible task of uniting the four states of his kingdom in order to stand a chance at winning the impending war. But he must do so on his own with a single warrior chosen by the heavens and he soon finds that she is someone he once met.
