If you're interested in these books, it's worth reading "We" by Yevgeny Zamyatin as I think it clearly inspired both:

A slightly different direction is take by Katherine Burdekin's Swastika Night, simultaneously more realistic and more fantastic, which is well worth checking out if 1930's dystopias are your thing.
