Crown of coral and pearl

"For generations, the princes of Ilara have married the most beautiful maidens from the ocean village of Varenia . . . . Nor once dreamed of seeing the wondrous wealth and beauty of Ilara . . . But when a childhood accident left her with a permanent scar, it became clear that her identical twin sister, Zadie, would likely be chosen to marry the Crown Prince . . . Then Zadie is gravely injured, and Nor is sent to Ilara in her place. To Nor's dismay, her future husband, Prince Ceren, is as forbidding and cold as his home . . . And as she grows closer to Ceren's brother, the charming Prince Talin, Nor uncovers startling truths about a failing royal bloodline, a murdered queen--and a plot to destroy the home she was once so eager to leave. In order to save her people, Nor must learn to negotiate the treacherous protocols of a court where lies reign and obsession rules. But discovering her own formidable strength may be the one move that costs her everything: the crown, Varenia and Zadie"--Amazon.
