This is one of my favourite SciFi books; I like Wyndham's style, it's rather twee, very 1950s rural England, reminds me of the early map of a game of Transport Tycoon game. And not much action, more of a slow burn of ideas. Trouble with Lichen is about longevity treatments, touches on class warfare and women's lib.<p>Another of his that I really like is The Outward Urge (with Lucas Parkes) on the idea of yearning for space travel as a heritable thing passed down several generations of a family, over an implied world war and shifting of nation powers.<p>Another good more popular one is The Midwich Cuckoos (filmed as The Village of the Damned); all the women in the village became pregnant overnight, what did it mean and what to do about it? (Spoiler below). "Midwich was not the only - or even the first - village to have a dayout".<p>One I liked less, Chocky, an alien "invasion" by telepathy which turned into a bland rushed lecture on wasting fossil fuels and had no interesting conclusion.<p>(spoiler: aliens)
