The only reason I put this as buy 'maybe' is that I wouldn't want to re-read it, but it is definitely, definitely worth reading once. And definitely worth making a selection of friends and family read it so you can discuss.
Thank you to the author, the publisher and the bookbag for my copy. We also have a review of [[Heroic Measures by Jill Ciment]].
If you like the sound of this, or want to try an act of god on a much larger scale, read [[X-isle by Steve Augarde]].
