Not bad, but not one of my favorite kids' books. The kids are kind of goody-goody, in my opinion, (even though the author keeps making a point of saying how hard it is for them to be good). They don't have much personality -- they're sort of generic turn-of-the-century English children, very concerned with being brave and honorable and good. They're not quite as bland as I'm making them sound, but the only signs of personality they have is that the oldest understands a bit more than the younger two and tries harder to be mature, the middle sibling (a boy) tries to be brave and daring and has maybe the hardest time being good, and the youngest child is always knocking things over or accidentally ripping her skirt or tripping over her shoelaces. They spend their time saving people from train accidents and making people's lives brighter.
