Digital Fortress

Why it’s on the list: Brown’s first novel — an NSA cryptography thriller about an unbreakable cipher and an agency that cannot read it.

Where I saw it: A reply to @SpencrGreenberg’s question on X, June 5, 2025 — “What non-fiction book taught you the most about how the world (or how humanity or society) really works?” — recovered from that thread and saved to Kyle’s Apple Note “Books To Read”. Thread: https://x.com/spencrgreenberg/status/1930639380424577198

A novel, offered in a thread asking for non-fiction. Recorded as Kyle’s line has it.
