The Adolescence of P‑1 is the first and (so far as I know) only work of science fiction by Thomas J. Ryan. Ryan is an enigmatic author about whom little is known. His middle name was Joseph and he was born in 1942; if he has died, that fact is not known to my sources. There is one other fact about Ryan that one can easily deduce from this novel: he was very familiar with the University of Waterloo as it existed in the early 1970s. His book was the first SF novel I had ever read that drew on places and institutions I found cosily familiar.
Our protagonist is Gregory Burgess, a student at the University of Waterloo, majoring in Honours Getting Laid, with a minor in Keeping His Marks Just High Enough to Avoid Expulsion. His indifference to hard study vanished when he first encountered a book on computer programming. Girls were forgotten as Burgess honed his hacking skills and began to amass files and resources to which he was not remotely entitled. He was talented, but not quite talented enough: UW spotted and expelled him.
