Read the page first. Then switch to Explore and tap a panel for its note, or to Ghost to see every first look in place.

Four sample pages from the annotated edition, which will follow the book. In it every page of the book faces its ghost page: the same page faded, with a note for each panel. Each note has two layers, a first look in plain words and a deeper one for the reader who wants more.
