Here Lies Arthur by Philip Reeve
The highly acclaimed novel from the unparalleled Philip Reeve-now in paperback. Gwyna is just a small girl, a mouse, when she is bound in service to Myrddin the bard-a traveller and spinner of tales. But Myrddin transforms her-into a goddess, a boy warrior, and a spy. Without Gwyna, Myrddin will not be able to work the most glorious transformation of all-and turn the leader of a raggle-taggle war-band into King Arthur, the greatest hero of all time. An ancient story and a brilliant allegory of our own times.
