Thomas of course did HP illustrated covers etc
He sent me this in 2015 and it's signed and doodled on title page- very nice!
Dan can see ghosts. See then, speak to them, and sometimes help them...for a price. In his third adventure, poltergeist activity is plaguing one of London's tallest, oddest buildings, the Shard. Dan must try to fight off an enraged spirit and a very much alive fraudulent medium, while saving a little girl, working out what his ghostly sidekick is hiding from him and not plummeting to his death. Some of those things will be easier than others. An exciting, funny urban fantasy with a dark gothic twist.
