Status Updates From Rama II (Rama, #2)

With the appearance of another spacecraft in our solar system, the reader meets a new crop of space explorers. These characters seem less well oiled than the first crew, more inclined to take personal risks..

This novel begins with a forward by Clarke himself. His narrative has an almost casual quality (he swears he never intended to write a sequel) in which he seems seems to accidentally find his way. He goes on to describe his novelization of 2001 and 2010. Clarke also describes his meeting and earlier working with Gentry Lee who I am guessing added the more R rated elements to Clarke’s narratives warned of.
