Just curious if anyone else has come across this... I download a lot of freebie books off Prolific Works. Occasionally books don't have covers just the words 'Unknown' or a mesh of numbers and letters, but always before if I open it it tells me the name of the book and the author. What do you do to add it as a book you've read if it doesn't? This one has no cover, no title, and no author anywhere in the book.
