Titles in this Set: 1. Deep Dark 2. Witch Light Description: Deep Dark The dark was deep; it opened like a cavernous mouth and swallowed the boy whole. Cassia Thorne leads a double life. By day, she sells ballads at Bartholomew Fair. By night she spends her evenings locked up in Fleet Prison. Cassia has plans of escaping both of these lives. But this year there are rumours of children being snatched off of the streets of London and no one willing to help. So Cassia decides to take matters into her own hands; with the help of a young pickpocket, Teo and her friend Felix, Cassia starts to investigate the disappearances. She soon discovers a sinister conspiracy at the heart of the city - mysterious men in blue coats and whispers of a beast that lives in the deep dark tunnels below the city. Can Cassia get to the bottom of the mystery and rescue the missing children before it's too late? Join Cassia and her friends on a spine-tingling supernatural adventure through the streets of London! Witch Light She held up the hagstone and she noticed something strange – a shimmering light like tiny clustered constellations. It was as though there were something illuminating from the girls. Cassia Thorne uncovered a conspiracy in the deep dark underbelly of London involving a mythical beast, but has been whisked away by her uncle to Ravening Hall, a bleak boarding school on the moors of Lancashire. Far away from everything she has known, Cassia struggles to find a place amongst the girls of the school – torn between fitting in with the perfect prefects and the rebellious and wild Martha Torrent. And something sinister happening at the school. At night there is a strange presence in Cassia’s room, growing stronger with each day. She spies older girls wandering out onto the moors at night. And the local children are terrified of a child-eating witch that haunts Pendle Hill. Suspecting another supernatural mystery, Cassia begins to investigate. Are the stories about the witches of Pendle Hill true? And what do they want with the girls of Ravening Hall?
