On Fennburn Island, triplets are born every generation, three queens who have equal rights to the throne and possess treasured magic. Mirabella is an elemental, capable of lighting flames at the tips and throwing a storm at people with a wave of her hand. Katarina is a poisoner, capable of eating deadly poison without even feeling a slight pain in her stomach. And Arsinoe, nature, can make the most beautiful flower in the world bloom... and control the fiercest lion. But the queen's coronation is not just a matter of royal origin. Sisters must fight. This is not a game to win, but a game of life or death. On the night the sisters turn sixteen, the battle will begin. And the queen who endures will receive the crown. If only it were that simple! Katarina cannot drink even the weakest poison, and Arsinoe, no matter how hard she tries, will not grow a weed... The two queens are shamefully pretending to try to stay on the island, and their powerful sister Mirabella is not much wiser. But alliances are already being formed, betrayals await around every corner, revenge slides behind the queens, and one thing is clear: the last queen may not be the strongest... but she will be the darkest.
