'The great fairy incident of 1822 was depicted in many paintings, the most famous of them being The Seelie Siege of London by an unknown painter with a penchant for alliteration.'
Jonathan Strange & Mr Norrell by Susanna Clarke is a behemoth of a book.
It's over 1000 pages of alternate history, set in a world where the titular characters are bringing magic back to England, against the backdrop of the Napoleonic Wars.
