Retail Kate Richmond, former army ranger and ISS operative, has seen a lot in her life. Sabotage, espionage, cyber theft, and assassination missions have all played their parts in her journey to becoming a viper. Nothing surprises her much any more, not even a full scale incursion of an alien race by the Merkiaari! When a battle in the Border Zone leaves a pirate ship crippled, boarded by Alliance Marines, and reveals information that links Kate's brother with a dead viper and a bunch of Merkiaari corpses, it's safe to say that she's surprised. It's time for the most important mission of her life. It's time to find her brother.
