The emerald atlas

Several years ago, Kate remembers that her mother left her, her sister and her brother in St. Mary's orphanage. Her mother told Kate to always stay with her siblings. So she had. They never stayed in one orphanage for so long. Each orphanage was worse than the other, and Edgar Allan Poe Home for Hopeless and Incorrigible Orphans, was truly horrible. In the series of events that come after this, they end up in a gloomy town called Cambridge Falls and they soon realized that it has no children. They were the only children in this so called "orphanage." But they soon find out why by discovering the horrible history of this town with time travel, magic, and a book called the Emerald Atlas.
