I've never seen that a publisher who's locking it's books would sell them different on different platforms. I just checked Andy Weir from his own website, it is all amazon / apple / google etc locked versions - or pulp-tree-and-ink.

But I'd be very happy to be wrong; have you got sites to recommend?

Do you use to eat your eggs sunny-side-up? (With the yellow still liquid?) If so, you should be safe. Or you've been lucky, I have no clue as to the prevalence of Salmonella in Brazil.

THANKS you're the best :)
