I spend a disproportionate amount of time working on my Page Ones. I want the reader to get into the rhythm of the book as quickly as possible, as well as the book’s voice and tone. So what you see here is a tightly controlled visual story flow with the panels containing a repeating rhythm of dialogue, as well as one of the key narrative devices of the book.
By having just the three panels, and by having that dialogue with the repeating content, the reader is, in theory anyways, keyed into the pace of the book, and will feel the shock of what comes next with the right timing.
Now, here’s why this pacing matters. In thirty days when you pick up number two, page 1 is going to match this page 1. The content will be new, but the style and format of the page is the same. This is to inspire a subconscious trigger for you, reminding you of the rhythm and pacing of the book last time. It lulls you back into the rhythm of the series in a subtle way, and requires less time for your mind to play catch up.
