Perfect for you if...

  • You love sprawling space opera with genuine stakes, where entire cities fall in the opening act and the hero has to improvise survival from inside enemy territory.
  • You're curious about the pulp sci-fi that inspired everything from Star Wars to Star Trek, and want to experience the originator before the imitators.
  • You enjoy hard-science plotting wrapped in adventure, where technology has rules and characters have to think their way out of impossible situations.

Maybe not for you if...

  • You expect character development and emotional complexity. Smith writes forward momentum over introspection, and his people are tools for the plot rather than the reverse.
  • You need romance or strong interpersonal dynamics to stay engaged. This is pure action and mechanism, with relationships serving the story's needs, not vice versa.
  • You prefer contemporary prose styles. The 1930s pulp voice and pacing will feel dated, even in a well-proofed edition.

About this book

Triplanetary is the first book in the Lensman series. The planet Nevia, located many light years from Earth's sun, is running out of iron, its primary energy source for the dominant amphibious race. The Nevians possess technology that can extract iron atoms from any material—rock, machinery, structures, and even human blood. They set their sights on Earth as a rich source of this element. A Nevian spacecraft descends on Earth, destroys Pittsburgh and its inhabitants, and departs with three human captives, including Conway Costigan, an undercover intelligence operative for the Triplanetary Patrol. From within the enemy ship, Costigan must find a way to defeat the Nevians before Earth's population is destroyed. E. E. "Doc" Smith is known as the "father of space opera." He created imaginative future worlds and intergalactic battles before the era of Robert Heinlein and Isaac Asimov, and decades before Star Wars and Star Trek. The Lensman series was one of five finalists for the Hugo Award for Best All-Time Series. This ebook has been professionally proofread for accuracy and readability on all devices.
