Two grieving sisters resolve to break a spell cast by evil fairies

After the death of their mother, Olivia and Nellie are shipped off to their great-aunt's house for the summer. Nine-year-old Olivia is not excited about the trip—she has to keep one eye on kind but eccentric Aunt Minty and the other on her younger sister, Nellie, who's been behaving oddly. But the summer takes an interesting turn when Olivia discovers an old fairy tale: the story of a group of children who, at a garden tea party, are turned into flowers. The garden sounds an awful lot like the one at Aunt Minty's house—could the flower children be real? If Olivia and Nellie can only locate the old tea set from the story, they might be able to break the spell.
