Alien: A Novel Download Do You Know Of A Good Fiction Novel On Communication With Alien Cultures, Beings; Conspiracy, Etc?

Do you know of a good fiction novel on communication with alien cultures, beings; conspiracy, etc? - alien: a novel download

I only saw the fire in the sky movie. Are there any good books (not too unlikely appearance but not the names of Corny) in communication with foreigners, visiting exotic cultures, etc.? Something like contact, perhaps with Jodie Foster and "Men in Black? Hitchhikers guide, but no. I do not like allegory or irony.

Thx!
