As I was reading this, I could easily see it being a time-slipping thriller movie with Charlize Theron in the title role. It’s a very visually compelling story of a hotel that is a stopover place for time travelers but then there’s some sort of anomaly that is hard to pin down leading to the hotel detective having to rty to figure stuff out all the while suffering from increasingly concerning “slippage” due to the mount of time travel she’s done. A lively book, with a bit of confusing timeline back and forth (not always easy to tell when “now” is which I think is intentional but still kind of vexing) but ultimately one that delivered.
