Extras[]
This volume has at least two pages of extras consisting of a cast list, with capsule descriptions of the major characters, at the beginning of the book. The full extent of the extras is not known with complete certainty, since the print edition of the book is still forthcoming.
Presumably, a cast list has been included in this volume, although one wasn't present in volumes in the First Journey, because books in the Second Journey are supposed to be a good starting point for new readers. The previous volumes (The First Journey of Agatha Heterodyne, books 1–13) did each include a summary of "The Story So Far" and a humorous capsule biography of the professors, which this volume omits.
