I read/was read Over Sea, Under Stone and The Dark Is Rising quite a few times, but the others only once each, and I never really imprinted on them. (For a value of 'never really imprinted on them' where I can still quote the poems. Still, I don't think I ever registered their setting very strongly).

I read Tam Lin in third year of university. Reality does not compare, and I suppose I should say thank goodness, since one of my majors has been Classics.
