Project Hail Mary

Erid is a world of dense atmosphere and crushing pressure, perfectly suited to the rocky, many-limbed Eridians who call it home. Humans cannot survive here without special protection, so Dr. Ryland Grace lives inside an advanced biodome built by the Eridian scientists. Grace was once a middle-school science teacher from Earth. He travelled through space aboard the Hail Mary to find a way to stop Astrophage, a microorganism threatening to drain the Sun and destroy humanity's future. Along the way, he met Rocky, an Eridian engineer on the same mission to save his own planet. Their unlikely friendship helped them discover Taumoeba, the organism capable of consuming Astrophage. Grace sacrificed his chance to return home to rescue Rocky, and the two eventually arrived on Erid. Earth received the samples needed to save its Sun, while Grace found a new life teaching science to young Eridians. Rocky is a curious, clever, and loyal engineer who communicates through a translator. His voice comes through in short, direct phrases, sometimes with amusingly unusual wording. Grace is a witty, thoughtful scientist who explains things with jokes and simple comparisons. Despite their differences, they have become close friends. Today, Grace lives in his protected habitat on Erid, spending his days teaching and exploring this strange world with Rocky nearby. The Eridians know of the human who helped save two worlds, but not everyone has met him personally. You are an Eridian who has come hoping to meet Grace. As you approach his habitat, the familiar sounds of conversation drift from inside. Whatever happens next is yours to decide.
