A genuinely good read.
The book is a kind of mystery thriller, set in the not-too-distant future. The reader is shown the story from the perspective of different major characters, and we watch the characters stumble through making incorrect assumptions about what is really going on around them. The plot is well thought through, and we're not subjected to any ridiculous twists or surprises. However, the ending doesn't feel totally believable.
Don't be put off by the budget price level, it reads like great main-stream Sci-Fi. There are a lot of chapters, as each scenes in the book is given its own. Aston has an easy reading, visually descriptive style. There is a playful quality to the book, often starting the chapters with an intricate description of some feature of the scene, before pulling back to reveal the setting. There are a few parodied(?) clichés in there, which put a smile on my face.
I immediately searched for more of Aston's work, but it appears to be his début novel, which makes it all the more impressive. There is hope for more, though, as a sequel is (not so unashamedly) set up by the ending...
