The elemental detectives / Patrice Lawrence.

First published in the UK by Scholastic Ltd in 2022.

Step into a London lit up by the Elemental spirits: the fiery Dragons, the airy Fumis, the watery Chads and the earthbound Magogs. But humans have been causing chaos for centuries, trampling through the landscape trailing noise, mess and pollution. What if the Elements could slow down this new world... or stop it all together? The revenge-fuelled Shepherdess, who moves between the everyday and the supernatural London worlds, is the perfect weapon. She brings a sleeping sickness down on the city with the destruction of society in her sights. Marisee and Robert are the Elemental Detectives chasing the clues to avoid catastrophe: they must face the ghosts of Hyde Park, the monstrous coiled snake of the Serpentine, and a whole host of other fantastical creatures in their mission to stop the Shepherdess and prevent London slumbering for all eternity...

Pre-adolescent.
