A wonderfully murky, carnivalesque world of intrigue, unexpected friendships and mysteries solved.

Sheba the wolf girl joins an unusual troupe of performers that includes Pyewacket, a witch's imp; Gigantus the giant and Sister Moon, a knife thrower. For the first time in her life she feels she might make true friends, and learn a real stage craft. But soon that's not all she has to think about . . .

Children are being sucked into the Thames and there have been strange sightings of a mechanical monster. The carnival troupe know first-hand that looks only tell half a story - they become determined to find these forgotten children. Perhaps they will unravel the mystery that has defied even the law!

Illustrated with black and white artwork from superstar illustrator, Sam Usher, and the first in a brand new series!
