Here is the factual background for the author's novel, Day of Immense Sun, which was published in June 1936. One gets echoes of the story and the characters as one traces with the author, her fascinating research into the amazing contrasts of Peru, old and new. She flies the distance from New York to Peru -- she plunges almost at once into the beauties and mysteries of an ancient civilization, on which a modern civilization has been superimposed. Her experiences thrust her now into one, now the other. Blair Niles is at her best in research and glorified reportorial work -- and this has moments of enchantment and beauty, though one sometimes feels that the vast mass of material has not been thoroughly digested. Sell for fireside travellers as well as those planning a trip to Peru.
