A twist of fate set events in motion, but it was Zach Marshall's ingenuity that had saved two worlds from Crimson's plague. But for what? While billions revered Zach for defeating Crimson and her plague, everything Zach loved had been taken from him and his faith had been shaken to its core.——Now, a year and a lifetime later, Zach is living on Ptain as Earth's Ambassador, working to build an alliance to ensure Earth's survival. But nothing is as it seems in this high stakes interplanetary game of power and intrigue. Even as Zach struggles to save humanity, he has to decide whether he has the courage to start his personal life over and risk everything once again—because Crimson is still out there, searching for Zach and Earth and revenge.——In the tradition and values of C. S. Lewis, with mental warfare on the scale of Asimov's Foundation and Empire, and featuring gripping battles and surprising twists reminiscent of Orson Scott Card's Ender's Game, Primal Screams is a thought-provoking, heart-pounding science fiction adventure that explores the essence of good and evil, while tackling profound ethical dilemmas of our time: cloning, planetary conservation, biological agents, nanotechnology, faith and family.
