The Starless World

Sanna Heikkinen crash-lands on a rogue planet hurtling through the void between stars — no sun, no rescue, no hope. Armed with sixty days of rations and a failing distress beacon, the astrophysicist fights to survive in frozen darkness. But deep beneath the surface, in a subterranean ocean warmed by the planet's molten core, she discovers something that rewrites everything humanity knows about life in the universe — and a warning that could determine whether civilization endures or falls.
