The winds of Mars have brought a storm to Sandrid. Astill Chrone is on the run and his friends with him, but the perilous trail of death follows and they must hasten, lest Markus Larton catch and kill each of them once and for all. Strange people surround the prince, hoping to lead him to glory but he is wary of them all. The Traitor still lurks and it could be any one of their new allies. Chrone finds himself leaving Sandrid behind, not knowing when he may return. In the southern wastelands, he discovers an evil truth of Mars. Human evolution is in full swing, and it has spread down different paths. As factions of transhumans, eugenic beings and inhuman wraiths emerge, he must discover who he is and choose his side. All the while, the rise of sentient AIs lies on the horizon, waiting to overrun humanity in its sweep. Titans fall and legends arise, as the rains of Mars come down.
