Project Hail Mary — Metadata

Orientation

Junior-high science teacher and former molecular biologist Ryland Grace wakes up alone aboard a starship called the Hail Mary — light-years from Earth, with amnesia, and with the desiccated corpses of his two crewmates beside him. As his memory returns in flashbacks, he learns that an interstellar microbe called Astrophage is dimming Earth's sun, and that he was sent on a one-way Hail Mary mission to the Tau Ceti system to find out why that star alone is unaffected. There he meets Rocky, a five-legged, ammonia-breathing alien engineer from 40 Eridani whose home star faces the same crisis. Two species, two desperate ships, one shared problem — and an unlikely friendship that has to crack the science before either civilization runs out of time.

Cover-at-a-glance

The 2021 Ballantine hardcover, designed by Will Staehle, is a black field broken by sweeping gold-paint gestures suggestive of stellar wind, comet trails, or the Petrova line itself. A tiny white astronaut figure floats at the upper right, tethered to nothing visible, dwarfed by the gold flares behind it. The author name and title are set in a confident, angular geometric sans-serif (sharp triangular A's, mechanical M's), white on the black background. A round "From the author of THE MARTIAN" seal sits to the right of the figure. Mood: cosmic isolation, hand-painted urgency against engineered precision, gold-on-black reverence for deep space.
