One of the things I notice these days when reading books is the repetition verbal tic that some authors develop. In Deathless Divide, the word "burble" stood out in its repeated use. In Peace Talks, the phrase "don't borrow trouble" showed up at least three times that I recall. Okay, yes, just looked up the count, three times: twice as "don't borrow trouble" and once as "You already have enough trouble without borrowing more." One has to wonder what is going on in Butcher's life when he wrote the book that the phrase was stuck in his head, coming out in his words.
