A large-scale Hollywood project created based on the “The Witcher's Apprentice” series – the film “The Seventh Son”! Watch it in January 2015 in all Russian cinemas! What does it feel like to know that the future of your country and, perhaps, the whole world will depend on you? Do you know that the devil himself is following in your footsteps? It's not for nothing that Tom Ward is called the Witcher's student - he managed to learn a lot from old John Gregory. But Tom is still only fourteen and he is simply not ready for some dangers. That is why Master Gregory decides to send him north, to the land of rivers, swamps and lakes. Bill Arkwright, himself once a student of the Witcher, agrees to take the young man in for six months and train him. And Tom sets off on a journey - to where the devil is preparing a suitable meeting for him... The book “The Witcher’s Mistake” is published in Russian for the first time!
