If its £20m for 4 books, would they give him the advance for all 4 at the same time? Wouldn't they wait to see how well Book 1 sold before investing in Book 2
The advance is paid no matter how the books do @Dinoteeth. Remember, it's an advance on royalties, so it's a gamble for the publisher who will have calculated how much they think they can earn. Once they agree the advance, the publisher is contractually bound to pay it, unless the manuscript is not delivered. If an author earns beyond the advance, s/he will get residual payments in the form of royalties every 18 months. The advance is at best a gamble. The larger the advance, the more motivated the publisher will be. I imagine Harry's publisher will be VERY motivated.
Would he/they really get the same amount for each book though? I’d have thought this book would be the one with the biggest advance because it’ll be the one with the biggest potential audience. And the work and “self” that goes into it will be greater than that of the wellness book.
That is a great point @RandomPenguinHouse. It may well be that the advance for the memoir is higher than for the others, but if I were his agent, I would negotiate equal value for each book so that the publisher is invested in each book. But you are right that different amounts may well have been allocated. Bottom line though is that only a third of 20 mill will have been paid, no matter the allocation per book.
Another curious question, if a boom is being release say 1st November how far in advance would they start printing it?
This is what is so strange with Harry's book @Dinoteeth . Normally , galley copies, or advance copies, are produced 3 to 6 months in advance of publishing, it's how reviewers manage to publish reviews the week a book is published, excerpts are arranged, eg with Courtiers and Angela LeviN's book on Camilla.
It also takes a massive amount of time to get books to UK shops, and the lucrative Commonwealth markets of Australia and New Zealand etc.
All of this tells me that harry's book is nowhere near ready, even factoring in HM The Queens's death.
My gut feeling is that this is a book that has been in trouble for some time.
