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. The first the two children encounter is a somewhat crotchety and unfriendly hobgoblin named Broom, who is (more or less) secretly looking after the farm.

After Elizabeth's husband dies, she begins to play her tenor saxophone again, and remembers when she was 15 and a member of the Blonde Bombshells, an all-girl (with one exception) swing band. Accompanied by the exception and urged on by her grand-daughter, Elizabeth hunts up all the old members of the band and urges them to perform, and in doing so, learns more than she knew about the band, its members, the roses on the drum set, and herself--the last of the Blonde Bombshells.
