As many people here have pointed out, this isn't a book so much as a collection of (sometimes edited) blog posts from Inger Mewburn's fantastic blog, The Thesis Whisperer. I've been following this blog for about three or four years now and it is consistently excellent with advice for academic research work and was useful to me for both my Masters and now that I'm starting my PhD. I think the fact that it's blog posts isn't really a problem for this book - Mewburn is upfront about what it is; the blog has become very large so it's quite nice to a have a selection of key posts at your fingertips without having to try to remember where you read them, the selected posts are relevant, interesting and easy to read, and finally the Kindle pricepoint is pretty reasonable for all this (although I think if you don't have some sort of device to read this on as an ebook, I probably wouldn't recommend it in hard copy given the content is all available online and the physical book is fairly pricey for what it is - I'd say go forth and bookmark your favourite articles instead).
Where it falls down, though, is with proofreading. This may seem like a petty criticism because overall Mewburn's writing is good and there's nothing there that renders the text unintelligible, but in a book that's essentially about writing, it's a bit disappointing, as well as being a little disturbing as you're reading along. The main problem is with missing words rather than typos. I've never noticed this as a particular problem on the blog, so I'm not sure what's happened there, but it would be great to get an update with the problems corrected.
Overall: useful, easy to read, but probably not worth forking out for a physical copy
