Deathworld
by Harrison, Harry
Jason dinAlt is a professional gambler who thinks he has seen it all, until he lands on Pyrrus. It is a planet where every living thing—from the grass to the beasts—is evolved to kill humans with brutal efficiency. The gravity is heavy, the wildlife is lethal, and the colonists are hard-bitten survivors who view Jason as a soft-handed outsider. This is pure, high-octane survival fiction. Harry Harrison keeps the pacing frantic, forcing you to constantly recalibrate your expectations alongside the protagonist. You will not find much room to breathe here; the book is a relentless exercise in human ingenuity pitted against a world that wants you dead. This is for readers who enjoy hard-edged science fiction where the environment is a character in its own right and the stakes never dip below existential.
