Very readable bit of 1950s-style pulp fiction. Concerns a group of humans in some futuristic time (yet, suspiciously, despite having invented manned space flight, not having progressed beyond boxed radio communications, hand-held compasses or helicopter transport, inventions which were the height of sophistication in 1951...) who are exploring a new planet and get embroiled in local politics despite supposedly not wanting to interfere.
Let's ignore the inconvenient plot holes, like the ability of the group to speak each other's language despite the humans never having visited the planet before, and the convenient physical similarities of the humans and the Avtini. This is, after all, pulp science fiction, and very enjoyable it is too.
The plot barrels along at a great pace, concerning mainly the societal structure of the Avtini who are modelled on a bee colony, centring around a dominant breeding female, and the profound influence which supposed neutral observers have in challenging this culture through befriending Iroedh, a sexless female, and her friend Antic, a male.
Much strife ensues, involving skirmishes, battles, coups and romantic dalliances. The bee-like culture is easy to understand. It is all very silly and could have done with inventing some futuristic technology rather than leaving the space travellers mired in 1950s tech. The concept of earth travellers selling their society to a primitive alien culture is all a bit uncomfortable. Nonetheless, still a good read 70 years later.
