Semiosis

I read the Semiosis duology by S. Burke and I loved it. It’s about a small colony of humans on another planet, Pax, their adventures with indigenous and visiting life-forms and in some ways even more alien fellow humans from distant Earth, which had been ravaged by the failing ecology and wars. The books comprising the series, Semiosis and Interference, are thoroughly engrossing, often unpredictable, subtly satirical, and gently suspenseful.
