The Substitute Bride by Samantha Cayto

Being a bride is a state of mind, not of body.

Lord Carwyn has come to the royal palace of Moorcondia to support his beloved cousin, Nora. The princess has been promised in marriage in order to bind a treaty between her country and the archipelago nation called The Southern Chain. His efforts to help her turn into a daring plan when he catches his first sight of Nora’ s intended. The foreigner captivates him in a way no other man ever has.
Kai Aleki feels the fate of his people on his shoulders. As his nation’ s military leader, he understands how duty always comes first and a strong alliance is crucial to fight the vicious marauders known only as the Swarm. He has no interest in marrying a woman but the delectable and attentive Carwyn captures his attention.
Carwyn has a solution that will satisfy everyone. He secretly takes Nora’s place and marries Aleki himself. A delighted Aleki sets off home, determined to protect the known world from the Swarm after safely delivering Carwyn to his new home. The dangerous venture holds hidden dangers, forcing Aleki and his bride to join forces to defeat a common enemy.
