The actual book I want to find is a collection of greek myths, a pale blue hardback, illustrated black and white which I read around 1990. It was old then and I was the only person who took it out of the school library. I even called the school to find out the author, the librarian remembered it but they'd recently moved into a new building and as I'd been the last person to take it out, they'd thrown it 
More realistically, I tend to read historical fiction, wouldn't be averse to a proper historical book, nothing too difficult (getting back into reading post DC), but not too boring. Or gory. Or scary. Or tear inducing.
