The sirens have been evacuated to a remote island after years of being pillaged and murdered for their ancestors crimes. Though the sirens enjoy their peaceful life on their new, lone island, food is growing scarce, resources are becoming more limited, and with no males in the species, reproduction is impossible. Ember has broken the rules before. She has swam to the human shores and seen humans. Unfortunately, it's not all the glamor that fairytales boast. She returns to the sea, battered and bloody, but her battle is over. Until she is chosen to go back to the humans. She is elected to marry a prince in need of a wife and strengthen bonds with the humans again, but the world she sees is worse than the one she fled from.

She's the runt, the outcast, the pack punching bag. All because she's different; a fox-in a pack of wolves. When an Alpha comes to evaluate the pack and discovers his mate abused and malnourished, he takes her back to his pack. The Alpha known as being cold, quick tempered and selfish, finds his salvation in a runt; his runt. In the middle of a war, can she find her place in the pack and can the pack accept that their new Luna is a meek fox? Can the Runt stand with the Alpha of the strongest pack?
