Fake Nim books an Amazon, which ones are real?

[Mrokii]

So... did I understand that correctly that the only book that is currently 
recommended (if at all) is the one by Andreas Rumpf? The 2nd doesn't sound 
appealing, as it only deals with a very old version of Nim. Or would that still 
be of any use, even though the examples aren't compatible with newer versions 
of Nim?
