Faeries

While waiting for their new home to be renovated, Nellie and her younger brother George are sent to a farm in the countryside, much to George's delight and Nellie's disgust. However, the farmhouse and the surrounding area are teeming with fey creatures, most of which Nellie cannot see initially because she doesn't believe in faeries. The first the two children encounter is a somewhat crotchety and unfriendly hobgoblin named Broom (whom Nellie can see) who is (more or less) secretly looking after the farm.
