If you haven’t yet read Usurpation, here’s your chance to buy it at a more economical price. The trade paperback will be released on Tuesday, October 21, available from any bookseller.

This is the third book in the Semiosis trilogy. As you may recall, Stevland, an aggressive, intelligent plant on a distant planet, longs to send his seeds to Earth. In the second book of the trilogy, Interference, he finds a way.

Now Stevland’s descendants grow everywhere, but no one on Earth knows they are intelligent, and humans have fallen into a violent crisis. They need help. But how? Stevland sends advice: “Compassion will give you courage. Love will be ferocious.”
