Written before some of the stories by Tchaikovsky with a similar premise, this was a short and fun read.

I don't think the writing of different species was anywhere near as mature or compelling as Tchaikovsky's stories, however the overarching plot - population control, nuclear war, and the environment was closer to home.

I liked that both species had flaws and specialities, but I wish a bit more time had been spent exploring their civilisations.
