Eighteen years ago, a vengeful slave used black magic to switch her newborn daughter with the White Wolf princess—and swapped their scents. The princess who should smell of white lilies woke up reeking of mud. The slave's daughter was wrapped in silk and given a ruby that only true royal blood can wear.Today, Elina scrubs floors and gets beaten for dreaming of becoming a knight. Roslyn wears diamonds and orders executions for fun. But when Elina’s White Wolf spirit erupts at the Royal Tournament, an ancient ruby rejects the imposter and flies across the courtyard to clasp itself around the slave’s neck. The kingdom gasps. Prince Arthur draws his sword—not for the princess, but for the girl in chains. And Roslyn? She starts to smell like rotting mud, no matter how much perfume she pours on.Fire cannot burn real royal blood. Torture cannot break a true wolf’s spirit. And no amount of lies can hide the stench of a stolen crown.
