I think this was the author's best novel yet in this series. Just the right amount of excitement. More like 4.5 stars.
After eight years away fighting in Greece, Sertorius returns home to his wife, Arrea, to find out he is tasked by the Senate to recruit new legionaries to fight other Italian tribes who are not citizens and as such lack their rights. He is made a quaestor [a junior magistrate.] He travels to the city of Mutina to fulfil his orders, along with Arrea and freedman and friend, Apollonius. Sulla is there and calls his legion "Sulla's Fist", hence the title. He becomes involved in what will be called the Social War [aka "War of the Allies."] His son Gavius, has joined Sulla's legion and of course, the young man's parents are worried about him. His boyhood friend, Lucius, is in the same legion. Arrea lives with a couple in the city. There will be battles, skirmishes, ambushes, poisoned wine, burning grain, and betrayals. Finally, Sulla and Marius work together for victory. Sertorius identifies a traitor but instead of killing the man, has him go into exile from the Roman Republic, among the Lusitanians. I assume Hispania will loom large in Sertorius's further story.
I liked the different points of view of several of the characters--Sertorius himself, Gavius, Arrea, and Lucius, also the fact they revealed their thoughts and feelings, not merely the action happening to and around each one. I found the ending most satisfactory and fitting, with its note of hope.
I thank the author for sending me a copy of this novel.
