Expected by his enemies to die the miserable death of a military slave, Kaladin survived to be given command of the royal bodyguards, a controversial first for a low-status "darkeyes".

The fifth book in the NYT best-selling Expanse series, Nemesis Games drives the crew of the Rocinante apart, and as they struggle to survive, the inner planets fall victim to an enemy's catastrophic plan. A thousand worlds have opened, and the greatest land rush in human history has begun. As wave after wave of colonists leave, the power structures of the old solar system begin to buckle. Ships are disappearing without a trace. Private armies are being secretly formed. The sole remaining protomolecule sample is stolen.

Warning: You may have a huge, invisible spider living in your skull. This is not a metaphor. You will dismiss this as ridiculous fearmongering. Dismissing things as ridiculous fearmongering is, in fact, the first symptom of parasitic spider infection - the creature secretes a chemical into the brain to stimulate skepticism, in order to prevent you from seeking a cure. That’s just as well, since the “cure” involves learning what a chain saw tastes like. You can’t feel the spider, because it controls your nerve endings.
