Star Crusades: Valentine Books in Order

Gravely wounded while boarding an enemy battleship, Marine Valentine receives a chance to return to combat. She must prove herself among the Novas, an experimental unit of cybernetic soldiers commanded by the enhanced Jotnar Captain Olik.

With Alliance forces retreating from a Ski'lig invasion, Valentine and the Novas help defend Deimos. Its Spacebridge controls the enemy's access to reinforcements, making the Martian moon the focus of a desperate siege alongside Marines and civilian militia.

Valentine and the Novas return to occupied Epsilon Eridani with an Alliance armada commanded by General Rivers. The technologically advanced Ski'ligs defend their conquests through aerial attacks and powerful warships, leaving the Novas to tackle the toughest assignments.

Rebuilt after the devastating battle on Deimos, Valentine returns determined to avenge her fallen comrades. As the Novas and their fleet prepare to strike back, she struggles with the increasingly blurred boundary between human and machine.
