"In winter nothing more dreary, in summer nothing more divine, than those glens shut in by hills and those bluff, bold swells of heath"

The contrast between summer and winter on the Yorkshire moors is as remarkable as Lockwood laments in this line. The seasons are representative of the book's extremes: the pure elation of Heathcliff and Cathy together and the innocent young summer days spent on the moor; then the icy misery their love becomes, represented by the cold winters and bleak isolation.
