Soul of Stone — Michele Amitrani

Every legend hides a truth as dangerous as a double-edged sword. On the far island of Sarpedon, a snake-haired she-monster known to inhabitants as the Soul of Stone turns people into statues. For decades, heroes from all over Greece have been trying to put an end to her evil, and for decades her collection of statues has grown, soul by soul. When Panacea, a young Amazon warrior with a talent for potions, learns her brother has been killed by the monster, she sails to Sarpedon to seek revenge. But in the killer's cave, Panacea makes a stunning discovery that leaves her questioning everything she believes to be true. Torn between bravery and fear, between loyalty and treachery, Panacea must reconcile herself to the knowledge that ending a life is easy, while preserving one is hard. Vengeance is an art—but is she willing to bathe her soul in Hellfire in order to master it?
