I'm just gonna say that the ability of the author to spell out a visual is by far the best in this book than any other I have read/listen to.
Marsters has really hit his stride with Harry's universe. Very enjoyable.
Other reviewers complained about file because it appears to jump (camp kaboom), but it's just a flashback when Harry is knocked out. I verified in the book, but (without the ellipses) there's no audio indication that it's a flashback.
