Publisher's Synopsis
What hides under a bed, eats chocolate ripple cake and sends letters in silver envelopes?
Whatever it is it's making strange and ominous noises and Henrietta is determined to trap it. To her surprise, the culprit is a mind reading, love-sick and very bossy fairy called Mabel May Hissop . . .
Mabel has a letter for Henrietta - it's an invitation to an magical ball, where fireflies and fairies dance the night away.
Fans of Henrietta's previous adventures will love this enchanting new adventure.
