The Secret Diary of Adrian Mole, Aged 13 ¾ is a peculiar sort of a novel. Its interest does not lie where the reader might expect.
In theory, Diary is, as the name suggests, a (comedic) epistolary novel, formed from the diary entries of a young boy navigating adolescence in England in the early 1980s. Taken as that, the reader will very soon develop an objection: Adrian Mole is not a teenage boy; Adrian Mole is a wholly unbelievable character written by an author who was evidently never a boy, and had not been a teenager for some time, and had largely forgotten what it was like.
