Man, I had the exact same thought when I started 'Paragon Hotel'. The setting feels so meticulously researched, doesn't it? That mix of jazz age glamour and simmering racial tensions in a segregated Portland feels painfully real. The author, Lyndsay Faye, is known for her historical deep-dives, and she nails the period details here.
I ended up down a rabbit hole looking into Portland's actual history, especially the Albina district. While the hotel itself is fictional, the backdrop of the Klan's presence in Oregon in the 1920s is terrifyingly factual. The novel uses that real-world ugliness as a pressure cooker. So, it's a fictional story built on a very real, and often overlooked, historical foundation. That's what got under my skin—knowing the prejudice Alice and Max face wasn't just a plot device.
