Dustjacket has no tears, but the back cover has some scuffs/scratches. Possibly unread?

omnibus of: OVER SEA, UNDER STONE (1965) + THE DARK IS RISING (1973) + GREENWITCH (1974) + THE GREY KING (1975; Newbury Award winner) + SILVER ON THE TREE (1977.) A re-collection of a set first combined in Britain with the title The Dark is Rising Sequence (1984.) This may be a good way to get this set in a durable format for cheap (but I dislike artists like Velez who can make anything look stupid.)
