Snorri Sturluson 
The Sagas of Olaf Tryggvason and of Harald The Tyrant (Harald Haardraade) [EPUB ebook] 

This book is about a great and rousing story of the last of the Viking kings, with truly incredible adventures. The highlight is not the language with flowery flourishes, but with jolting, abrupt changes in plot. There is no inner-dialogue, and the dialogue between characters is direct but halting, with little fluidity. It is obvious that this is an ancient text and a translation.
