From Enterbrain:
The tale of William Tell has never been rendered this beautifully as in Mitsuhisa Kuji's stunning debut work Wolfsmund, where a fortified barrier-station torments the Swiss Alliance murdering all who stand against it, until William and his son attempt to defy it.
A fascinating reimagining of a European legend, Wolfsmund is a retelling of the William Tell legend with a focus on an actual landmark in the Uri district of Switzerland, the Devil's Bridge at St. Gotthard Pass. Filled with action, politics and drama it has all the makings of The Game of Thrones, including its share of bloodbaths, but told through a historical fiction perspective.
