After reading Hitoshi Iwaaki's 'Parasite', i had to read Historie, and i got to say, my personal opinions on this series is that it is pretty damn good.

the plot itself revolves around Eumenes, and his childhood, who would later in his life grow up to be the secretary and general to Alexander the Great.

Yes, it is a 'Historical' manga, but its actually very interesting, although i will admit it starts off a bit rough, but if you give it a chance and read more and more, it becomes very, very enjoyable.
