There are certainly better triathlon books out there, but this does at least give a good general and demystifying overview of the sport for the beginner, and digs down into more detail as you advance. But I couldn't see myself going back to this once I have acquired practical knowledge. It's fairly well written, with brief flashes of wry humour to lighten the mood. But frankly, its very dull to look at. It is laid out like they used to publish in the 80s - mostly long-form text with only a few photos and box-outs/charts/tables. For someone who has grown used to the brilliant Men's Health/Runners World style books, this makes reading it more of a haul than a pleasure. I only paid a few quid for this among a selection of other tri books, so I'm happy, but if you only want to buy one book, don't make it this one!
