The beautiful and kind princess Sophie should soon ascend to the throne. But the evil queen, Sophie's stepmother, considers her stepdaughter too soft-hearted. For ruthless people, there is nothing more harmful than kindness. Rulers should not know pity. They must show neither weakness nor fear. Wanting to maintain power, the queen orders the huntsman to kill Sophie and take her heart. However, seven forest men save the girl by replacing her heart with a clockwork... And now Sophie faces a difficult choice: hide, accept the cruel rule of the queen, or fight. "Iron Heart" is another interpretation of the story of Snow White, told by Jennifer Donnelly, author bestsellers “Tea Rose” and “Sister”, winner of numerous awards, in particular the Carnegie Medal. For the first time in Russian!
