Riley Bloom series

After crossing the bridge into the afterlife, a place called Here where the time is always Now, Riley's existence continues in much the same way as when she was alive until she is given the job of Soul Catcher and, together with her teacher Bodhi, returns to earth for her first assignment, a ghost called the Radiant Boy who has been haunting an English castle for centuries and resisted all previous attempts to get him across the bridge.

Eager to contact her sister Ever, ghost Riley goes in search of the place where dreams are made, where she finds a renegade ghost boy who has been flouting the rules of Dreamland for decades.
