Hi Ammit, I recently read a book from a french author called "Enquete sur des Extraterrestres qui sont deja parmi nous" ( Investigation of ETs who already live among us). I don't think there's an english translation. It was written in the late 90s. The author relates his investigations about a group of ETs called Ummo (Ummit in french) who came to earth to study humans. It is said that they lived in the mountains ( Alps, I think ) and they use to communicate with some scientists and other people from Spain via letters. They were tall and blond. ( nothing to do with the Tall Whites ) Some say they looked like Norwegians. Very interesting book, but also a lot of scientific stuff that makes it hard to stay focus.
Here's a link about the author:
