Two sisters, Nor and Zadie, are twins and best friends who live in a village where villagers reside in houses on stilts in the ocean. Their mother has planned and prepared for them to be valid princesses so the Elders can choose one of them for the prince’s wife when he’s ready to rule. Nor has a scar on her face caused by a scrape against a blood coral so the villagers assume that Zadie or Alys will be chosen by the Elders. Zadie and Nor have been best friends with Sami since they were young and now Zadie and Sami are in love, so Zadie doesn’t want to leave home. Nor has always wanted to explore the world beyond the village. When Zadie is chosen, she’s desperate to do anything to stay with Sami. After she acts on her desperation, Nor’s life is turned upside down. She travels to New Castle in the mountains far away from home so she can meet and marry the prince who turns out to be cold and unkind. Nor gathers some allies and vows to do everything she can to take care of her family, village and the kingdom she’s going to be the princess of someday. 5 stars for this fantasy involving sibling sacrifice and strength!
