Inside Rama, they find several city-sized clusters of objects and a central cylindrical sea, but no life and no controlling AI. As Rama gets closer to the sun, it warms up and comes to life, meaning strange robotic life forms start appearing and doing things the crew don't understand. One of the crew explores deeper into the interior (in a very contrived way!) and has to be rescued, which brings some elements of danger into the novel (which up to this point has been a “space procedural”).
