Book of Secrets links all editions of Fennel's Journal together. With 14 Journals in the series, and 14 core chapters in this book, it's the 'one book to bind them all' with each chapter providing the continuity story from one Journal to the next.

Containing Fennel's previously private writing, it provides the 'other side to the story', explaining why a slow-paced rural life - and dogged determination to pursue one's dreams - is so important.
