This was a book clearly aimed at a much younger reader than me, so I had to clear my mindset of all adult expectations, and attempt to see it through the eyes of a teenager. I enjoyed the basic plot line very much, Carl is a young man with much to blame the world for, his parents are dead from a senseless car accident, he's been sent to live with an uncaring, unsympathetic uncle, he's unpopular at school, being considered a bit of a nerd, due to his passionate interest in the heavens and all things interstellar, and only seems to have one friend, the sports jock, Mike. Then, a new girl, Grace, starts at his school, and life becomes a whole lot more interesting for Carl.
I found myself really liking Carl, despite or maybe because of, all the adversity in his life, he is an extremely nice young man, no bad boy attitude, no vices, he's polite and punctual (possibly a little too perfect, I would have accepted, even expected, a little bit of angst and attitude to be present), but, Carl is genuinely a very likable character.
The pace is a little slow in the beginning, but then soon hots up as strange, inexplicable things begin to happen to Carl and he realises his life will never be the same again. His relationship with Grace soon develops, and I couldn't help wondering, if this was because of the desperate loneliness of his life, that any girl showing an interest in him would have been instantly the focus of his obsession. When Grace reveals herself as the very embodiment of his lifelong interest, it's more or less a done deal, that she will become the love of his young life.
Maybe, because of this interest, Carl deals well with all the shocks and surprises thrown his way, again, perhaps because he so desperately wants those shocks and surprises to be true, he never really questions any of them, but accepts what he is told at face value. I found this a little naive, surely, even someone as young and lonely as Carl, should have questioned the intentions of Grace and her alien community, and the motives of the aliens, I couldn't really get to grips with. Quite why they were alerting the world to the possibility of alien visitors, by faking crop circles and UFO sightings, was something I was a little unclear of.
The final portion of the book really does deliver though, with evil, deranged, military, commanders pursuing them at every turn of the page, Carl having to help save the friendly aliens, and come up with plans and new plans, and an ending that satisfied, even if the adult, mum, part of me couldn't help thinking he'd come to regret his decision.
Overall, an entertaining read, only losing a star because of the predictability of a lot of the plot, the fact it's just not a genre I generally read and enjoy, and the desperate need for more commas.
