Five years. Two top performers. One promotion. Absolutely no intention of playing nice.

Katie Brennan and Nate Callahan are the best VantagePoint Technology Group has to offer—and each other's favorite professional problem. Their rivalry is legendary: ruthless competition, razor-sharp banter, and an irritating tendency to make each other better.

When an executive position opens and they're named the final two candidates, years of competition finally have a finish line. There's just one complication: proving they deserve the job will require them to work together.

High-stakes clients. Late nights. Business travel. Too much proximity. And the increasingly inconvenient realization that perhaps five years of mutual irritation hasn't been entirely professional.

Tools of Engagement is an interactive workplace rivals-to-lovers story about ambition, attraction, and two equally formidable adults discovering that wanting each other doesn't mean either intends to lose.
