The Earth is saved (by three flatmates)
I have said before in reviews that I do enjoy a good sci-fi comedy, but they are hard to come by. This book is certainly one of them, and I enjoyed every page. Like most stories of this sub-genre, the actual plot is less important than the antics of the protagonists, but here goes.
An intergalactic conman talks the world’s leaders into selling the Earth in return for paying of the entire planetary debt. Of course once it has been sold, the new owners plan to sell it off again, to be turned into a galactic holiday resort, a process that involves changing the climate and ultimately destroying the Earth. Discovering this minor unmentioned fact, our three heroes (or two heroes and one heroine) set out to foil the resale process and buy the Earth back, traveling across the galaxy with the aid of what amounts to a teleportation device (if somewhat old fashioned and just a little rusty), an elderly professor, his housekeeper and a hedgehog. How they go about saving the Earth would be too much of a spoiler, so you will have to read it yourself to find out that.
Well written, just slightly absurd (as it should be) and thoroughly enjoyable. The best I have read since Douglas Adams. I recommend it to anyone.
