I might be slightly biased here, as I am a Gimlette fan (Gimletteer, is the right term?), but I'll be fair & say that although I enjoyed this book, including some truly laugh out moments of wry observation & historical fact/fiction, it was slightly more difficult to really feel I had travelled to Newfoundland & Labrador, as you felt in "Pig" & Paraguay.
Plenty of positives: Humour still in abundance, some fascinating figures (though I would've liked a bit more insight into some other living people - Jim Baird got loads of lines, but he didn't seem to me to really deserve that amount - some of the Labradorians did, I felt), a heck of a lot of historical anecdotes & knowledge, once again, easily readable & memorable. Also, kudos to John for not believing the nonsense about the Viking settlement - if you read Wikipedia it's complete tosh on the same settlement - you feel a one-up having read this.
Negatives? Not many, and not in any way to really detract from the book But...
I can't read French. Maybe my fault (yet I speak Spanish fluently), but I really do detest constant usage of French as if we SHOULD all know that. It's my pet bookwriting hate. It was smattered around, but there was still too much presuming.
Some of the Labrador places were repetitive. It's always good to explore ever nook & cranny, but it lurched towards same old, same old with many places.
More photos would've been good, particulary of the modern day. I just couldn't really get in my head visually images of some of the places visited.
HOWEVER...
Overall, the book was excellent - well written, readable, nice pace, humour, it introduced the wonderful Wilfred Grenfell to me & I have learnt a lot more about a place which, in truth, I never cared about, let alone knew about. That is now different, as is my opinion of Innus & Inuits. As far as I'm concerned, if an author can do that, then he/she has done well.
Not as good as "Pig" (but then John's actual living background is more personal there, than Newfoundland is), but still head & shoulders over much of the dirge that makes up current travel writing.
