Enchanted Glass, by Diana Wynne Jones

Academic Andrew Hope has forgotten most of what he learned about magic as a child from his grandfather. When he inherits his grandfather’s house and his field-of–care, Andrew is at a bit of a loss. Orphaned Aidan needs Andrew’s help in fending off both the authorities and his magical stalkers. Luckily he is able to help in return with Andrew’s magical memory problem. Easily blending the magical and real worlds, Diana Wynne Jones brings her usual mix of complex human interactions, romance, adventure and humour to the last novel published in her lifetime. The slightly ambiguous ending leaves open the possibility of a sequel, but it was not to be. Her death from cancer in 2011 was a sad loss to the world of fantasy writing. It is such a pity there will be no more of these wonderful books, but at least there is the joy of re-reading the favourites.
