Second Stage Lensmen

The blend of classic pulp style with sci-fi elements gives this book its unique flavor. I'm curious how much of that was intentional and how it evolved during writing.

For a pulp adventure, the diplomatic scenes added depth, but I wonder if that was a deliberate choice or just part of the fun.

The concept of the Lens and its abilities was fascinating and integral to the story. I'm curious whether this was based on earlier sci-fi ideas or something original.
