- Description from novelbuddy

With A Tale of Blades & Blood, the world of Avalion takes shape in the form of an all too familiar world. Filled with morals either clear or grey, war is inevitable while peace never lasts. Fifteen centuries of watchful peace and subtle tension have finally boiled, and the conflict rises once more, now filled with more bloodshed than ever before.Beyond the mountains of the Nortenhein, the Weslands arm themselves to take back their lands and bring forth to the south and the east A Bloody Winter. To the east, over hills and through forests of old and past the waters of the Red River, The East Plains stand tall with the Spire as its center, ready to fulfill their Dream of Vengeance. Deep in the south where the cities stand and to the west where the walls never crumble, steel meets steel as brother fights brother in A Dance of Fire and Swords.Witness the adventures of Orevian Ballister, Norien Ravenhan, Forien Strix, and Loran Aelond as they face battles of wits, blades, honor, glory, and tragedy in a story that shall never be forgotten:A Tale of Blades & Blood.
