In the cursed Kingdom of Aragoa, the punishment for magic is death. Even the students at Vandenberghe Academy aren't spared. When Viola Sinclair's deadly shadow magic is discovered, the queen gives her assassin a new assignment and a new cursed tattoo: seven-thorned rose on his arm for the seven days he has to hunt Viola down and kill her. If he doesn't, he will be the one to die. The assassin is Roze Roquelart -- entitled prince, arrogant fellow student, and the one person Viola hates more than anyone. Roze should revel in the chance to end her life, but he desperately needs something from Viola and her magic. And he's willing to spare her life -- and fake their engagement -- to get it. Forced to work together, Viola and Roze must contend with deadly threats, dangerous secrets, and an impossible attraction. Will they give in to their deepest desires, even if it means destroying Aragoa -- and risking both their lives?
