Abaddon’s Gate, book three in the expanse series by James S. A. Corey.

This is excellent space-opera, which finds James Holden once again caught up in the events surrounding the gate constructed by the Protomolecule at the end of the second novel.

More deaths, and what appears to be a seemingly insurmountable mystery, but one which could open up opportunities for humanity, such massive opportunities as which have never been seen before.

Great read!
