The Stoneheart trilogy is a set of three children's novels by Charlie Fletcher, published between 2006 and 2008. The three novels in the trilogy are Stoneheart, Ironhand, and Silvertongue. The trilogy follows two children, George and Edie, as they struggle to survive a war between the animated statues of London. The war takes place in a second reality, which overlays modern London. Thus the children and statues can see and interact with the reality of the normal world, but the people in that reality are unaware of the second reality around them. Source: Wikipedia (en)
