As usual Robert Charles Wilson places his characters in the relatively near future and realistic, which sees the emergence of insoluble and inexplicable phenomenon. A time warp in "Spin", a small village teletransporte in a parallel dimension in "Mysterium", and here the incongruous burst giant totems straight from the future. The main error that can be committed by opening a book of Wilson would be expected to explain the causes of such intriguing phenomena. Attracted by the summary, I confess I too misguided, as it is clear that, good god, we would like to know why and how come things like that! That's not the point. If the fantastic vein Wilson is more effective and documented (allow a few aspirins when addressing the explanations of quantum physics), it is above all a subtle humanist who is interested in these extraordinary events that have repercussions on his characters . For once, it is felt. However, the novel does not end still in the absolute fog, but offers fine hypotheses, for deepening that have elegance to bet on the intelligence and sensitivity of its readership.
