I read 451 when I was 12 and in my anything-science-fiction phase. It is one of maybe three of them that I reread a few year later. Bradbury and Theodore Sturgeon were mu favorite authors.
I cut my Sci-Fi teeth on them - along with Asimov, Heinlein and a double handful of others. Might as well add Ursula Le Guin, and (at an early age) Andre Norton, just to keep from being sexist
