Avery Cole knows exactly how to survive a crisis: keep her voice steady, her strategy sharper, and her heart nowhere near the office.

Then Northstar Creative hires her back?and assigns her to work beside Julian Hart, the polished strategist who once beat her for partner and has been infuriatingly impossible to forget ever since.

Julian has a plan for winning Northstar's biggest account. Avery has a plan for proving he cannot be trusted. Neither plan includes sharing a glass-walled office, working until midnight, or pretending to be in love when a publicity scandal threatens the company's future.

Their fake relationship comes with rules: no jealousy, no public improvisation, and absolutely no falling for each other. But forced proximity has a way of turning old rivalry into dangerous chemistry, especially when every staged kiss feels less like strategy and more like surrender.

As a corporate leak puts their careers?and the people they lead?at risk, Avery and Julian must decide what they are willing to lose for the truth. Because the most complicated rule in the workplace is the one neither of them can keep: never mix business with pleasure.

The Workplace Rulebook is a smart, witty contemporary office romance about enemies who know exactly how to push each other's buttons, a fake relationship that becomes impossible to fake, and the kind of love that refuses to stay inside the lines.
