It’s Not PMS, It’s You by Rich Amooi

Ruth “Ruthless” Harper is on the verge of becoming managing partner at her all-male consulting firm and she won’t let anything stand in her way. That includes men, relationships, and that dreaded F word, FEELINGS—distractions she eliminated long ago.
After the worst day ever (a near-death experience and a public wedgie, for starters), Ruth realizes she doesn’t want to live and die alone. She puts together a business plan to find the perfect man and dives head first into the murky online dating pool. All she wants is a high-powered executive who understands how important her career is. If only it were that easy.
Problem is most men are intimidated by Ruth’s confidence and shocked by her bluntness. The exception being her landscape designer, Nick, whose cool demeanor and unsolicited dating advice are driving her nuts. He’s the antithesis of the business-oriented man Ruth envisions for herself, so why do all signs keep pointing back to him?
