The Legion Chronicles

Sergeant Davis had been in the US Marines for seven years when he stumbled into a knife fight outside the local bar. He ended up killing the wrong alien. Now, as a human who interfered with a galactic plot and killed a Confederation enforcer, his actions sentenced Earth to die. His only choice: desert the Corps and take the punishment on himself.

It seems like the Roswell aliens have been helping us all along. While the conspiracy theorists were right, there are alien lizards wearing people suits. The alien plan is to trick the Earth into breaking a law humanity knows nothing about so that they can sterilize the planet and take it for their own.

Join William Tell Davis, a Roswell alien, and a computer being called Marvin as they save Earth from a plot to destroy it, by creating a secret military force called the Legion.
