About This Book
The sharp scent of soggy metal and salt fills the air as Chess and his friends sail their creaky air raft over the endless sea of thick, swirling white fog. Below, the world is lost beneath a deadly mist, but above, on the Rooftop, adventure waits—and danger lurks closer than ever. With every gust of wind, their hope to save Mrs. E grows stronger, but so does the shadow of Lord Kodoc, chasing them through the clouds.
