But the not-very-highbrow truth of the matter was that the reading was how I got my ya-yas out.For the sake of my bookish reputation I upgraded to Tolstoy and Steinbeck before I understood them, but my dark secret was that really, I preferred the junk. The Dragonriders of Pern, Flowers in the Attic, The Clan of the Cave Bear. This stuff was like my stash of Playboys under the mattress.
