D: Heavy Water – A Gripping Historical Espionage Thriller Set on the Eve of World War II (Bomb Light Book 2)

Neal Stephenson

A large sepia-toned portrait with blue-lensed sunglasses sits within a collage of aircraft, buildings, control panels, and a horse and rider, framed by bold red, white, yellow, and blue shapes. The grey uppercase title “D: HEAVY WATER” runs vertically along the left; the yellow uppercase author name “NEAL STEPHENSON” spans the bottom.
