From Italy to USA, through Brazil and Russia, this book is a report on contactees, close encounters of the third kind and of abductions as well. José Antonio da Silva, Antonio La Rubia, Charles Hickson or Fortunato Zanfretta, you name it.

From the 1970s, in then the world-wide press, cases of presumed abductions begin to appear with always greater insistence, in the course of the which mysterious entities would have tried to establish some kind of contact with the humans. Such episodes, that ufologists will begin to classify as "close encounters of the fourth kind", will replace the already famous and richest casebooks of the third type, simple encounters without the contact with aliens. Since then, therefore, still monstrous giants with green eyes and fluorescent skinned demons, blond venusians and bug-eyed little men, all with one new and specific purpose: to establish a communication with earthlings, for an unknown aim.

Reaching a huge series of witnessings, some of which rare, Degli Esposti exposes with method such files. Overall, a rather good book... Even though it stops at telling stories.
