In a harsh sub-arctic world, surrounded by adults who are most of them, variously, defeated in love, Eli and Oscar make the perfect connection. They become mates- brilliant mates- but adolescence lies just ahead and Oscar will go over the edge and Eli never will. In a matter of months he will have to choose between immortality- barred from the sunlight, always on the run- or the ageing process that will turn him into a duplicate of Hakan- the creepy, middle-aged retainer he has replaced, living on memories and killing to service his mistress in return for the occasional, bored caress. Eli and Oscar are damned. Eli knows (how could she not?) Oscar doesn't- not yet- but he will.
