The Hedge Of Mist

Tom doesn't like fiction books or any of that mumbo jumbo stuff. For him it's facts and science. So when he reads an old book of medieval Welsh tales and finds himself sent to an Otherworld (whilst standing between two mirrors, of all things) he has to explain it to himself with science. But when he befriends Hannah, who is trapped inside the Otherworld, will it be magic or logic that rescues her?
