Jethro Goes to War (Jethro:The Wandering Engineer Book 1)

When the wandering engineer was forced out of Pyrax he left a small but growing group of military officers and enlisted. These men, women, and non humans are determined to restore the Federation despite the corrupt politicians standing in their way. They have to pick up the pieces Fleet Admiral Irons has left behind and soldier on without him in the hope that he'll return someday.
Jethro is one of those people, a new marine recruit. He's a Neo Panther, a member of the Anvil cat clan, and although he's young, he's a professional assassin and ready and eager to prove himself.
Perhaps too eager.
To what lengths will he go to fight for what's right? Will his first taste of true combat be his last? But first will he survive Boot camp and the infamous F platoon's Neo drill sergeant?

This is the beginning of his story.
