Thanks! I just saw Peter Woit's post on the Abel Prize https://www.math.columbia.edu/~woit/wordpress/?p=13877 also speaks positively about that book.

I've been reading it over the past few days (picked it up after seeing it mentioned here). It's fantastic, much better than many similar attempts to make quantum field theory comprehensible to mathematicians.
