The sequel to the hugely popular Echogenesis. Fifty years on from the previous expedition, the crew of another lander has arrived on Aranyani and made their home on a high mesa isolated from the surrounding forest. There, they can be safe from the deadly Howlers - or so they think. But Sam can't help wondering if his changes to the Tsiolkovsky's programming have really worked. He believes his will be the final expedition - but what if he's wrong? And even as he ponders, his son, Gramm, is busy exploring the coast of Aranyani's largest continent, more than a thousand kilometres away - where he makes a shocking discovery that upends everything his father has come to believe.
