365 Days of UFOs: A Year of Alien Encounters is that book, which is available now.
Below is the book description:
"In the pages of his new book, Nick Redfern presents 365 of his favorite UFO stories - one for every day of the year. Spanning decades and continents, they cover numerous subjects, including the Roswell UFO crash, Men in Black, Mothman, face-to-face encounters with extraterrestrials, military pilots and UFOs, crashed flying saucers, and cosmic cover-ups."
A very interesting idea for a book!
