Outcast Marines is a ten-book series by James David Victor, published entirely in 2019. The story begins with Outcasts of Earth, establishing a group of disgraced marines who must prove themselves through dangerous missions. The Kepler Rescue, The Titan Gambit, and subsequent books throw them into escalating alien conflicts.
The series builds toward an invasion storyline spanning Proxima and Pluto before concluding with Command Code and Conquest of Earth. Victor published all ten books within a single year, giving the series a rapid momentum that matches its nonstop action.
