Fuzzy Nation★★★★★
John Scalzi Not sure it's better, but it is more enjoyable than the original, with better characterization and less deus-ex-machina. Same overall story of colonization, corporate greed, enviromnental exploitation and who counts as people, but different enough to enjoy both.
Little Fuzzy★★★★☆
H. Beam Piper An enjoyable tale of first contact, colonialism, environmental stewardship, corporate greed vs. ethics, and most importantly, who counts as "people" on an alien world that turns out not to be uninhabited after all.
Semiosis★★★★★
Sue Burke A fascinating take on space colonization, intelligence, and language, following multiple generations of humans on a world dominated by sapient plants.
The Lathe of Heaven★★★★★
Ursula K. Le Guin A surreal tale of dreams changing reality, global stakes anchored by the three people involved. Be careful what you wish for.
