First published in Australia in 1937 when Kenneth Mackenzie was in his early 20s, “The Young Desire It” is a book to set beside James Joyce’s “A Portrait of the Artist as a Young Man,” Alain-Fournier’s “The Lost Domain” and . . . well, I don’t know what else. In his excellent, though plot-spoiler-rich introduction to this Text Classics edition, David Malouf adds Raymond Radiguet’s “The Devil in the Flesh,” but mainly because its author was a comparably gifted prodigy (Radiguet died at 20).
