Second in the "Hyddenworld" series. Half-human, half-hydden, Jack is still struggling to decide which world he belongs in, but one thing is certain: he must reunite the four gems in time for the Shield-Maiden to wield them. If he fails, both the Hydden world and the human world will face extinction. Finding the gems is hard enough; he also has to face the fact that the Shield-Maiden is his teenage daughter, who is just as unsure of her destiny as he is.
