Rowan is visiting her aunt - Winne the hedge witch - in the Welsh countryside, to get back to nature and hone her skills, as well as taking a break from her annoying sisters and enjoying some peace and quiet. However, Rowan soon comes to realise that hedges are a serious business and this isn't quite the opportunity to rest and escape she thought it might be.
Not only that, but mysterious events around the town are causing panic in the secret magical community and cowans - non-magical folk - are starting to take notice.
Can Rowan hone her hedge craft, try to make some friends and solve the riddle of the mysterious goings-on, or is magic about to be revealed to the world ... or at least Wales?
