This is Director Graeme Harper's production diary from some episodes of series 2 and 3 of the new run, including the series 2 finale "Doomsday", and series 3' "42" and "Utopia". It's an interesting insight into the day-to-day process of making a Doctor Who episode, and is packed with quite a few fun anecdotes about the show's cast.
Graeme Harper also worked on the classic series of Doctor Who, and the blurb on the back makes something of the fact that Harper compares working on the original series to working on the new one- however the chapter "How It Used To Work" is literally FIVE PAGES long, which was by far the most disappointing thing about the book. If Harper could've spent a bit longer telling stories of the 'olden days' this would've been a truly fascinating read for all Whovians, but that's a missed opportunity there.
At times the diary is a little bit dry- too many dates and dry production information, not quite enough personality- but mostly it's a decent read, and worth reading for a Who fan or if you're interested in working in TV.
