Writing in brg #104 (February 2019), Bruce Gillespie writes:

An author who understands the essence of good fiction is David Grigg, a Melbourne author and fan. He published a few YA novels in the mid 1970s in Australia, then was waylaid by Real Life for many years. Now he has retired, he has written The Fallen Sun, a slow-moving and very satisfactory novel set on a version of Earth, strangely altered. The book is based on us getting to know the characters through the difficult journeys they take. The feeling is melancholic although the story is told as a series of adventures.
