The Water Fairy Tribe is rejoining Fairydom after cutting itself off generations ago—and is releasing thousands of surface fairy prisoners. Among the surface tribes, the announcement that they will be reunited with loved ones long thought dead has evoked a passionate response.

Crown Prince Isaac of the Wood Fairies would love to make Lady Cassidy of the Water Fairies his wife—and future queen. Although she worries this will anger many of his tribe, he is confident that he knows a way to help others see her for the valiant, honorable woman she is.

When Cassidy agrees to accompany Isaac on a scouting expedition to secure a village site for some of the political prisoners her tribe is releasing, she has only second-hand knowledge of the dangers they'll face. Predators, ice, and a fear she's never known all await her in the Deep Woods.

Will the risk and sacrifice be enough to turn the tide in their favor?
