Amber gives a superb talk here. I couldn't help but contrast her delivery - fluent , articulate , without any notes - not even a rostrum or podium to hide behind - with the numerous talks and items I heard when I was a JW.

I am reading her book " Leaving the Witness " just now - it is superb - I just can't put it down. Strongly recommended.
