Yes, the unthinkable is about to happen: Murderbot must voluntarily speak to humans! Again!

The Hygrometric Dehabitation Region, or the "Zone," is a growing band of rainforest on the equator, where the heat and humidity make it impossible for warm-blooded animals to survive. A human being without protection in the Zone is dead in minutes. Twenty years ago, Marks went into the rainforest with a group of researchers led by Doctor Elaine Fell, to study the extraordinary climate and see if it could be used in agriculture. The only thing she learned was that the Zone was no place for people. There were deaths, and the program was cut short. Now, they're sending her back in.
