Emily of New Moon by Lucy Maud Montgomery

-"I wonder," thought Emily, "how much longer I have to live."

She had prowled that evening farther down the bay shore than she had ever gone before. It was a warm, windy evening, the air was resinous and sweet; the bay a misty turquoise. That part of the shore whereon she found herself seemed as lonely and virgin as if no human foot had ever trodden it, save for a tiny, tricksy path, slender as red thread and bordered by great, green, velvety sheets of moss, that wound in and out of the big firs and scrub spruces. The banks grew steeper and rockier as she went on and finally the little path vanished altogether in a plot of bracken. Emily was just turning to go back when she caught sight of a magnificent spray of farewell-summer, growing far out on the edge of the bank. She must get it--she had never seen farewell-summers of so dark and rich a purple. She stepped out to reach them--the treacherous mossy soil gave way under her feet and slid down the steep slope. Emily made a frantic attempt to scramble back but the harder she tried, the faster went the landslide, carrying her with it. In a moment it would pass the slope and go over the brink of the rocks, straight to the boulder-strewn shore thirty feet below. Emily had one dreadful moment of terror and despair; and then she found that the clump of mossy earth which had broken away had held on a narrow ledge of rock, half hanging over it; and she was lying on the clump. It seemed to her that the slightest movement on her part would send it over, straight to the cruel boulders underneath.
