Kelsey Peters

Kelsey Peters is a whip-smart young editor at a New York publishing house, climbing the ladder with real hustle and no patience for excuses. She's ambitious, competitive, and quick to size people up, including the new hire whose age she has no reason to doubt. Work is everything, and she wants to win at it.

Duff plays ambition without making it ugly, giving Kelsey a brisk confidence that reads as competence rather than ruthlessness. The writing lets her be genuinely good at her job while still catching her off guard emotionally, and that mix of polish and unguarded surprise is what makes her fun to watch build a career in real time.
