Short does not mean slight, and Seeing in the Dark makes the case in under three hours. Wellbeing, personal development and spirituality all claim the title in our data, and work sitting across all three is almost always concerned with meaning rather than method.
The format matters here more than usual. At two and a half hours, read by the author, this is closer to a spoken teaching than to a book that happens to have been recorded. That is a distinct tradition in audio, one where the voice is not a delivery mechanism for the text but part of the text itself.
The byline our catalogue holds carries a doctorate, and the register of the work is accordingly serious. The mode, though, is oral, intimate and unhurried rather than academic.
