The Core Plot

The story follows Dr. Ryland Grace, a former molecular biologist turned middle-school science teacher, who wakes up from a long coma aboard a spacecraft. He suffers from severe amnesia and discovers that his two crewmates are dead. As his memory gradually returns via flashbacks, he piece together the terrifying truth: a space-dwelling microbe named Astrophage is consuming the Sun’s energy, triggering an ice age that will destroy life on Earth. Grace has been sent light-years away to Tau Ceti, the only nearby star unaffected by the microbe, to find a cure. The mission is a literal “Hail Mary”—he must use his scientific ingenuity to solve the mystery alone. However, everything changes when he encounters an alien spacecraft and makes first contact with an unlikely ally.
