The world we know is only the beginning. Beneath the surface and between the moonbeams is another, more magical realm. All magic comes from this place, through doorways that only the fairies can open. And at its centre is the Fairythorn Tree -- the oldest tree in any garden, wood or park, and home to the tiny fairies who live in its branches.

When a Big threatens to cut down the Fairythorn Tree, only Fleur's beautiful singing voice can save the day. But she's too scared to sing in public. Can she overcome her fear to protect her home and her friends?
