#Co-Worker Books in Order

The #Co-Worker series is a two-book workplace duet that starts with office pranks and ends up knee-deep in commitment, jealousy, and the realities of marriage. It follows Presley Malone and Haden Cooper, colleagues whose mutual loathing turns into the kind of chemistry neither of them can control.

In the story first published as #Jerk and later revised as The Office Rival, Presley is the hyper-organised co-worker who keeps her personal life far away from the cubicles. Haden is the arrogant office golden boy who gets under her skin for sport. A bad day, too many sharp words, and a reckless encounter explode their rivalry into something physical. What begins as a one-time mistake and a petty game quickly becomes an obsession that neither of them can keep behind closed doors.

The sequel, originally titled #B!TCH and re-released as The Marriage Rival, catches up with Presley and Haden after they have done the hard thing and actually built a life together. They are married, raising a son, and still working under the same roof. Old habits die hard, and the same competitiveness and sharp banter that once made their chemistry fun now start to chip away at their trust when work, parenting, and outside temptations pile on.

Across both books, Masen leans into the messier side of office romance. There are pranks, public arguments, and plenty of heat, but the heart of the series is watching two flawed people learn how to turn a volatile fling into a partnership that can survive once the adrenaline wears off. The recommended reading order is simple: start with The Office Rival (or its original #Jerk edition), then move on to The Marriage Rival (previously #B!TCH) to see whether Presley and Haden can figure out how to stop fighting each other and start fighting for their marriage.
