What Are Common Challenges Writing Suspense Using First-Person POV?

The biggest hurdle I've run into is managing information flow. In third-person limited, you can always hop over to another character's head if the protagonist shouldn't know something yet. With first-person, you're stuck. I had to get so creative about planting clues my narrator could plausibly miss or misinterpret, without making them seem dumb. It's a tightrope walk between an unreliable narrator that's intriguing versus one that just frustrates readers. And the voice, oh god, the voice. It can't just be your own writing style projected onto a character. Every sentence has to feel filtered through their specific psychology, education, and mood. After a few chapters, slipping out of that headspace for a paragraph feels like a clanging gear shift. I find myself reading dialogue aloud just to check if it sounds like something they'd actually say, not just something I'd write. The constraint ends up being the whole point, though. That intense, claustrophobic intimacy is what makes the form sing when it works.

Man, 2nd person is a beast. Everyone says it feels gimmicky or like a choose-your-own-adventure book, but I think the biggest hurdle is maintaining immersion without making the reader feel bossed around. You have to describe actions and thoughts for 'you' that the actual reader might not relate to, and that disconnect can throw someone out of the story instantly. It requires an incredibly precise control of tone. I tried writing a short piece in it once, and I kept slipping into first or third person without noticing. The narrative voice wants to revert to what's familiar. Getting the descriptions right—like, 'you feel the cold metal'—without it sounding like an instruction manual or a therapy exercise is way harder than it looks. The few times it works, like in 'Bright Lights, Big City', it's because the 'you' is so specific it becomes a character of its own, almost a third person disguised. Most attempts just end up feeling claustrophobic.
