Space. Book 5. Nemesis Games

The paths to thousands of worlds suddenly opened before humanity, and the hunt for colonies began, like never before in its history. Wave after wave of settlers are sent into space, while back on their home planet, in the Solar System, state power is catastrophically weakening.
Ships disappear without a trace. Private armies are secretly formed. The last sample of the protomolecule has been stolen. Terrorists achieve what they once could only dream of — the subjugation of the inner planets. The reckoning for old sins has come, and the price is monstrous.
Meanwhile, amidst the fire and blood, a new order is being born, and James Holden and the crew of the 'Rocinante' are forced to fight to survive and return home.
