Congrats Stephen! I can’t wait 
I’m not sure if it’ll be feasible for a book like this, but could you try and make it e-reader friendly if at all possible please? (More details in my Programming Ecto (Pragprog) - #40 by AstonJ review.)
Can you also share some brief details about the book and what it might cover? Personally I’d love to see how to use LiveView for things like site-wide notifications and it would be great if you cover such a topic 
I’m guessing you already have, but it may also be worth looking through the liveview tag to see what people have been trying to do with it (which might give you some ideas for the book).
Good luck and please keep us updated
