Oops.... didn't spot that - saw "Amazon", then "ebook", and linked the two in my sad excuse for a reasoning process........
Sorry !!!!
More tea needed....
Again, you may have to buy used from same place (UK=£4-48), although I see on Simon & Shyster's "hook" Google ref the following :-
"TIME AND AGAIN will be released on October 02, 2008 in eBook ..."
Fairly definite, I'd've thought.....
So perhaps an email to said publishers might wake 'em up ?
