This is the first Philip Reeve book I've read that I did not consider a worthy read. Note that its not aimed at me, but at a much younger audience, and for them it may well be good, but there were too many cliches and tropes here for my taste and even for a children's book I can't condone that kind of lazy writing.
Whether it would be discernible to its intended audience, I don't know, but it was blatantly obvious from he start what was going on here. Emily lives at an interplanetary unfair situated on a moon somewhere, and visited by aliens of all stripes (and dots and heliotrope!). On the day the story starts, she bids goodbye to her parental units - an odd couple - only to discover that a unfair inspector has arrived and is a nasty piece of work. She sets off to inform her guardians.
What's obvious is that this is no fun-fair inspector. He's an unfair inspector - some dude who is sabotaging the fair by use of little spiky spidery type critters while pretending to fail everything because of poor maintenance and so on. No one sees this, or even suspects it. This tells me that everyone at the fair, and in particular Emily, is really rather stupid. I do not appreciate stories about stupid people (unless the author is planning on taking it somewhere interesting) and especially not about stupid female characters.
My other problem with this was the aliens. Like far too many sci-fi stories, the aliens were caricatures. And yes, it's a kids book, but multiple eyes on stalks? If only sci-fi authors had paid attention during the evolution module in school they would come up with far more engaging aliens. Most of this is on McIntyre since she was the artist, but the author doubtlessly could have nixed these drawings had he wanted.
That wasn't the biggest problem though. That problem was Emily. She was purportedly alien (there's no word about where she came from or how she ended up there) but she looks exactly like a human - except for a tail tacked on to her. It would have been nice had Emily been shown as alien, so kids understand there are interesting stories to be told about people who are not like the reader.
So all told, I DNF'd this and cannot commend it as a worthy read.
