Gilbert M. Stack impressed with The Fire Islands -- Volume I in his Legionnaire Series. This seems to be a trend for the chronicled adventures of Marcus Venandus - Tribune. The Sea of Grass is a rousing tale of adventure where we are again immersed in Stack's imaginary empire which only gains more and more depth with each volume. I found this novel quicker to absorb than The Fire Islands, having a background this go-round with the terminology.
As with any fantasy based on the Roman era, battles and intrigues are rife. These intrigues Marcus is quickly learning to thread, coming off exactly as one would wish of a hero - he doesn't care for the politics of being a soldier. It is in the heat of confrontation where Marcus' true brilliance is realized as he is able to scrounge from what little he has on-hand to come up with stratagem after stratagem to fight his enemies -- in this instance a horde of barbaric savages against whom Marcus must martial his defenses in the form of a rag tag band of legionnaires and a bunch of civilians among whom he is traveling.
It doesn't help matters that the mysterious shaman rebel rouser is a magician who is able to call down the lightnings! Beware, Marcus!
