The Tomorrow Windows is - at last - the first truly standalone Eight Doctor novel in a few years, and concerns a group of protected 'heritage' planets, and an alien estate agents plan to manipulate the indigenous populations into self-destruction so he can sell on the planets. This is very obviously a comedy in the Douglas Adams fashion (there's even some Slartifartbast-style planet designing), and though it's nowhere near as amusing as Adams work the frantic pace of the novel and the huge range of locations and bizarre aliens means this book is never boring. A bit hit and miss, and the plot is so far-fetched it would never survive in a non-comedy book, but all in all this is an entertaining and enjoyable read.
