The epic post-human story of Ramez Naam’s Nexus trilogy has finally come to an end—and the final volume, Apex, is coming out as an audiobook. And we’ve got an excerpt. Meet the intelligences that are set to replace us, and find out why “the next few minutes will decide the future of intelligence on planet Earth.”

The audiobook of Nexus, narrated by Stephanie Canon, is out tomorrow, but is already up for preorder at Audible.com.
