Indeed if we are adding supplementary material on top of the necessary changes requested during agency review 1, I’m afraid we must go for a second review. I can also check with Tom whether there is a grey zone so that we can avoid a second review, otherwise
I’m afraid the book will be published later than what were initially targeting.
