Attraction is the deadliest weapon.

Angelica is the top student at Assassin University, ruthless and determined to succeed in the male-dominated world of Departure Day Coordination. But cocky Jason aims to take her spot—and he doesn't care whose toes he steps on in the process.

When Angelica tries to teach Jason a lesson with a series of lethal pranks, he retaliates, and their bitter rivalry escalates into an all-out war. Dodging each other's dangerous surprises by day, the feuding assassins try to one-up each other with increasingly extreme antics.

But when the competitive pair gets paired up for a deadly class project, their simmering hatred might just transform into something even more dangerous. Thrust together into life-threatening peril, they're forced to rely on each other to survive.

As tensions boil over, Angelica starts to suspect there's more to Jason than meets the eye. Is this just a fling? Or the real thing?

The line between disdain and desire is razor thin, and getting involved with a rival is playing with fire. But at Assassin U, risking your life—and heart—comes with the territory. And succumbing to temptation can get you killed.
