On the planet Pyrrus, human colonists have fought a centuries-old war with the native life forms. These life forms adapt to human tactics and technology, evolving new species so rapidly that natives returning from even brief trips off planet must be carried in protective armor canisters from their ship to the safe buildings, where they will learn of the latest deadly threats. "The Ethical Engineer" is the second volume in the DEATHWORLD series. It was originally published as a two-part serial in ANALOG magazine in 1963.

"HARRY HARRISON IS ONE OF SCIENCE FICTION’S MOST PROLIFIC AND ACCOMPLISHED CRAFTSMEN." —The New York Times Book Review In the midst of Civil War, a stunned North and South join forces to combat a sudden attack of British troops. Though the Americans are victorious, three years later a new threat emerges. Her Majesty’s Army is massing for a possible attack through Texas. Into the gauntlet Lincoln sends his chosen angel of death, General Ulysses S. Grant—while his top soldiers, including Robert E. Lee and William Tecumseh Sherman, plan the most daring naval invasion ever launched: an assault on British soil itself. Stars and Stripes in Peril is the new masterwork from one of the world’s most provocative authors. Venturing beyond a fascinating question of what if? Harry Harrison brilliantly examines the people and passions that make up nations both great and small—and shows how technology and politics had the power to shape history’s first great World War . . . half a century before it began . . . "Lovers of novels of alternate history hold Harry Harrison in high regard and his latest book can only enhance that esteem." —Abilene Reporter News
