1. "Cats' Paws and Catapults: Mechanical Worlds of Nature and People" by Steven Vogel. If you were fascinated by the wings of birds or little waves behind the plants in water read this. Fascinating book!
2. "The meme machine" by Susan Blackmore. Starting off where Dawkin's book ended.
3. "Three steps to yes" by Gene Bedell, beside Getting to Yes already mentioned here.
