This was just a poorly done book and truly hard to get through. Ranging, anecdotal and only pretending to follow some kind of organization to tie together its poorly edited two- to three-page chapters, _Handing on the Fire_ takes the longest possible route for a 120-page book to not really answer with any clarity what "makes spiritual direction Ignatian."
Tetlow is a legend, so more than anything, this book just disappoints me—from its lack of clear direction over the course of its chapters to its awkwardly constructed sentences and glaring typos. It's not enough to have something to say, as Tetlow surely does in his decades of wisdom and stories, if it's not carefully and thoughtfully crafted to a clear purpose. But sadly, this may simply be a hurried work rushed to press in Tetlow's own final chapter.
In the end, every chapter concludes with four or so bullet points that restate its key takeaways (even though Chapter 16 repeats one for good measure), so in all honesty, you could just read those and get there a lot faster.
