After an embarrassing loss to her ex-girlfriend in their first basketball game of the season, seventeen-year-old Scottie Zajac gets into a fender bender with the worst possible person: her nemesis, Irene Abraham, head cheerleader for the Fighting Reindeer.

Irene is as mean as she is beautiful, so Scottie makes a point to keep her distance. When the accident sends Irene's car to the shop for weeks' worth of repairs and the girls are forced to carpool, their rocky start only gets bumpier.

But when an opportunity arises for Scottie to get back at her toxic ex-and climb her school's social ladder-she bribes Irene into an elaborate fake- dating scheme that threatens to reveal some very real feelings.
