I was in a bookstore slump, grabbing anything with a dramatic title, and that's how I found this. The core plot is a 'forced proximity' situation built on a massive lie. The female lead pretends to be a completely different person to escape her past, but ends up living right next door to the male lead, who is somehow connected to the life she's running from. It’s less about the 'can't escape' literally and more about the psychological trap of building a new identity that's still within arm's reach of everything you fear.
The novel spends a lot of time on the paranoia of maintaining the lie. Every shared elevator ride, every casual conversation in the hallway, is laced with this incredible tension. You keep waiting for the other shoe to drop, and when it finally does, the confrontation isn't just about the revelation, but about all the genuine feelings that grew in the middle of the deception. Honestly, the middle section where they're circling each other, both hiding things, is the strongest part.
