Spook's: A New Darkness by Joseph Delaney
Girls are dying in mysterious circumstances...They are found dead in their beds, covered in blood, with a look of pure horror on their faces. Worse still, their ghosts are left to walk the earth, just waiting for someone to hear the terror that has befallen them. Thomas Ward is the local spook - it's his job to protect the county from things that go bump in the night. But this is no ordinary haunting, and he finds himself on the path of a dangerous beast that is looking to kill again. He soon realizes this beast is just the beginning. An army of monsters is massing in the north, and it poses a threat to all mankind. This is the first terrifying tale in the Starblade Chronicles, from the bestselling author of The Spook's Apprentice.
