According to the late John Bright-Holmes, who came within a whisker of buying the first draft for George Allen & Unwin, this is an 'interesting and rather fascinating' book.
According to an expert reviewer, this is a 'perfectly extraordinary book', and the writer has an imagination of 'astonishing breadth and fertility'.
The reviewer describes the planet in which the adventure is set as 'a moralistic parable-version of our own; and with a wealth of consistent and lavish invention which almost suggests Tolkien, the author has devised a complete history for it, economic and political and social, underpinning this with a similarly complete structure of these people's religion, their philosophy, their science, their symbolism, their mode of spacial perception - everything you can think of, and nearly all of it deeply interesting'.
He concludes 'I was fascinated; and if a writer can fascinate weary old me, he must be a bloody marvel'.
A truly extraordinary book.
