What an interesting premise! Radiation from a dying star causes everyone over the age of 13 to die off leaving children in charge of the world. In the short time span that this is discovered, adults race against the clock to teach children all they know about everything from nuclear power to postal routes. A lot of action in the first 100 pages & I want to find out what happens once the children begin their roles as leaders of the new world. The only thing that I'm not crazy about is the cover. It isn't terrible, but I'm not sure it would grab my attention as someone who doesn't primarily read science fiction.
