Bounty is a one time upgrade which doubles the production of most basic types of Trimp workers for the duration of the run.
If you don't purchase the upgrade before clearing the Dimension of Anger, you can gain the achievement "Forgot Something"
When you find the book, it adds information about it under the Looting tab of the latest feed - "It's all shiny and stuff. You're pretty sure you've never seen a book this shiny."
The description of the provided upgrade states "This book will teach your Farmers, Lumberjacks, Miners, Scientists, and Explorers to all be twice as productive."
