Normally considered to be 'bad hat'* but I am replying to (updating) my
own post.
I read the sampler and found it good.
As clearly stated elsewhere - this is not a Discworld book, but it
remains to be seen (or not) if it is the same world as Nation or another
'Long Earth' like the one in Nation but not the same. However, one part
of the plot already revealed in the book would mean that is is probably
not strictly this Earth.
I will have to wait until it is released and as well as a dreaded e-book
I will probably be getting a hard back to keep my furnishing**
collection going ;-)
*whatever that means ;-) possibly a mishear on my behalf
