In 1424 Hamlin, Katerina faces threats from all sides. An outbreak of rats has overtaken the village, a mysterious beast is on a killing rampage of the village’s children, and Katerina’s evil stepfather is a dark presence inside the walls of her own home. Katerina is determined to hunt and kill the Beast of Hamlin herself before more lives are lost. When Steffan, the handsome but brash duke’s son, comes to town seeking glory and reward, Katerina decides he might be the ally she’s been looking for—even though the only gentle thing about him seems to be the sweet music he plays on his pipe. But there’s more to Steffan than she suspects, and she finds herself drawn to him despite her misgivings. Together Katerina and Steffan must stop the enemy from stealing the children of Hamlin. But their interference might create an even worse fate for the entire village.
