I had this delivered from the US, and have now finished the story along with the majority of the puzzles contained in it - I've missed two somewhere, and searching the town after the end credits hasn't shed any light as to where they are.
It's ... as good as the first. The puzzles may be a little easier in general, but there were a couple that caused me to stop and get stuck - the knight's tour puzzles in particular. I dropped a few picarats due to dodgily-worded puzzles as well; the one that sticks in my mind was the one where it said that New York was three hours earlier than San Francisco, when it actually meant later. Huff.
Thoroughly recommended, though - and I can't wait for the next.
