It's hard to know what to say about this book. Leonard really gives the sense of having some very good ideas in this book, that of time travel being used to sell package holidays being one of them, showcasing the effects that the fall of the Timelords has had. The scope of the book really is huge, and characterisation is also strong. The book's written, however, in a way that makes it almost incomprehensible. For the most part, I had little idea what was happening. The chapters do not take place in any linear order, and there are multiple versions of each event and character as the timelines begin to unravel and overlap. Whilst this is another great idea, the execution of it here results in little more than chaos. The book is very well written, and each of the individual chapters is reasonably enjoyable, but how they're meant to make up a coherent whole I have no idea. As someone else who read the book commented, the majority of the book could be replaced with 'And then some stuff happened' and the plot would progress just as clearly. I've heard of one reader producing a flow-chart from the events here in an effort to work out exactly what happens - but if a book takes that much effort to understand, then how can it ever be classed as enjoyable? I'm all for challenging books, and my favourites in the range are usually those that challenge and innovate, but this is just a muddle.
