Traitor of the Tides

Traitor of the Tides opens Frost Kay's Banished Queen Saga with an enemies-to-lovers arranged marriage between two rulers who each have their own reasons to distrust the other. Mer Thalassan, an exiled sirenidae princess marked a traitor by her own people, is sold to the Methian king to further a plan of revenge for the love she lost. The king, meanwhile, needs the marriage alliance to save his empire from a deadly plague and gets a bride who tries to kill him before she'll ever consider loving him. The romance builds slowly across a court full of secrets and a kingdom in crisis, ending on a cliffhanger that leaves several threads deliberately unresolved for the sequel.
