A review by spoth
Odd John and Sirius by Olaf Stapledon

3.0

Two books in one, written just before and during WWII - some pretty early-day science fiction. Reads like a Sherlock Holmes story, complete with semi-anonymous gentleman narrator.

Both stories deal with nature vs nurture (and racial superiority/inferiority) in ways that are cringeworthy at times but would probably make rich fodder for a term paper.
