Jupiter War

In the cold reaches of space, are they sowing the seeds of battle? Alan Saul is now part human and part machine, and our solar system isn't big enough to hold him. He craves the stars, but can't leave yet. His sister Var is trapped on Mars, on the wrong side of a rebellion. And Saul's human side won't let her die. He must leave Argus Station to stage a dangerous rescue - but mutiny is brewing on board. Serene Galahad is the earth's latest dictator, with its full powers at her disposal - and she'll do anything to prevent Saul from escaping her grasp. So she musters new warships, ready to unleash a terrifying display of interstellar violence. The previous ship sent to end Saul failed, and is now limping back to earth. One survivor is Clay Ruger, who is holding to ransom humanity's greatest asset - seeds to rebuild a dying Earth. He'll give them up if Galahad gives up her life. But will Galahad pay the price, to ensure humanity's future?
