Query: mostly by Walter Hooper

The main story contains two chapters by Lewis and the rest by Walter Hooper who tried to make a novel out of the two Lewis chapters many years after the death of Lewis. You can really tell the difference between the two authors. Hooper's chapters contain Americanisms, theological statements opposite to that of the beliefs of Lewis, and a writing style emphasizing physical actions and not thought processes.The dead giveaway is that 20% of the novel contains detailed descriptions of apparatus and their use. Lewis hated with a purple peeve such items in literature.Hooper has also rewritten much of the poetry of Lewis to exclude the allusions to classical Greek and Roman literature.For more information read "Light in the Shadowlands" and "The C. S. Lewis Hoax". Both books are written by a friend of Lewis.
