It has been a long time since young September bid farewell to Fairyland, and she
is excited to see it again; but upon her return she is shocked to find that her
friends have been losing their shadows, and therefore their magic, to the kingd
om of Fairyland-Below. It spells certain disaster and September won't stand for
it. Determined to make amends, she travels down into the underworld where, among
creatures of ice and moonlight, she encounters a face she recognizes all too we
ll: Halloween, the Hollow Queen. Only then does September realize what she must
do to save Fairyland from slipping into the mundane world forever.
