Ever since they first met, Catalina and Riley have been locked in a relentless battle for the top spot. Catalina, the sharp-tongued perfectionist from a wealthy family, has always had everything handed to her-except victory over Riley. Riley, fiercely independent and raised in the foster system, has fought for every achievement she's earned. From academic competitions to class president elections, their rivalry consumes them both. Every encounter is charged with tension, each insult carefully crafted to cut deep. But when they're paired together for a semester-long project, their worlds collide in ways neither expects. As secrets are accidentally uncovered and late-night study sessions blur the lines between competition and companionship, the walls they've built begin to crack. The closer they get to understanding one another, the harder it becomes to remember why they were enemies in the first place.
