What is the author's style in Song of Kali by Dan Simmons?

Song of Kali by Dan Simmons uses as a narrator an obscure but promising American poet who has some professional familiarity with two deceased Bengali poets, the indisputably great Rabindranath Tagore (a real person) and M. Das (an invented character, Tagore's disciple). Prestigious Harper's magazine hires Robert C. ("Bobby") Luczak to fly to Calcutta, India, pick up a newly-found manuscript ascribed to Das, and attempt to interview him, if rumors about him being alive are true.
