A generation after Harry Potter, a strange and beautiful new pair of twins appear at Hogwarts: they are Tinuviel and Thorondil, halfelven brother and sister. Their mother was an elf of Mirkwood, their father a wizard from Potters Bar. Being of mixed race, they can see and do things that others their age can't. This story began as a dream my daughter had (she was 10 at the time).
