Tress is an unremarkable girl who lives on an unremarkable island. It’s situated in the middle of a sea of green spores that fall from the moon. She washes windows, collects cups and cares for her family. But what Tress doesn’t want to admit, even to herself, is that she is in love with the duke’s son, Charlie. And he reciprocates those feelings.
When Charlie’s parents whisk him away to choose a bride, Charlie vows he will never love anyone but Tress. As the weeks pass, Tress begins to hope Charlie has figured out how to escape an arranged marriage. Then she receives terrible news: Charlie has been captured by the evil sorceress.
The sorceress’ island lies the Midnight Sea, a treacherous place where few dare to travel. But Tress is determined to rescue the man she loves.
And so she embarks on a journey filled with danger, loss and friendship that will challenge her as nothing ever has. Charlie’s fate rests in her hands alone, and she can only hope that she won’t let him down.
