Dangerous Ages is a Fiction Short Story Book. The book tells that the Neville, at five o'clock (Nature's time, not man's) on the morning of her birthday, woke from the dream broken sleep of summer dawns, hot with the burden of two sheets and a blanket, roused by the multitudinous silver calling of a world full of birds. They chattered and bickered about the creepered house, shrill and sweet, like a hundred brooks running together down steep rocky places after snow. And, not like brooks, and strangely unlike birds, like, in fact, nothing in the world except a cuckoo clock, a cuckoo shouted foolishly in the lowest boughs of the great elm across the silver lawn. Neville turned on her face, cupped her small, pale, tanned face in her sunburnt hands, and looked out with sleepy violet eyes. The sharp joy of the young day struck into her as she breathed it through the wide window. She shivered ecstatically as it blew coldly onto her bare throat and chest, and forgot the restless birthday bitterness of the night; forgot how she had lain and thought "Another year gone, and nothing done yet. Soon all the years will be gone, and nothing ever will be done". Done by her, she, of course, meant, as all who are familiar with birthdays will know. But what was something and what was nothing, neither she nor others with birthdays could satisfactorily define. They have lived, they have eaten, drunk, loved, bathed, suffered, talked, danced in the night and rejoiced in the dawn, warmed, in fact, both hands before the fire of life, but still they are not ready to depart. For they are behindhand with time, obsessed with so many worlds, so much to do, the petty done, the undone vast. It depressed Milton when he turned twenty three; it depresses all those with vain and ambitious temperaments at least once a year. Some call it remorse for wasted days, and are proud of it; others call it vanity, discontent or greed, and are ashamed of it. It makes no difference either way.
