An all-new steamy and angsty billionaire fake dating romance from the USA Today & Wall Street Journal bestselling author, Tracy Lorraine From the wrong side of the tracks to the heart of a billionaire… Leaving my hometown, I chased a single dream: work for Callahan Enterprises and build a better life for my brothers and me. The allure of city life, with all its glitz and glamour, promised a fresh start. I was determined to leave my past in the rearview mirror. But I didn’t bank on my demanding new boss. Kian Callahan is everything I can’t stand: entitled, arrogant, overbearing—not to mention a charismatic playboy. And the worst part? He’s also my best friend’s brother-in-law. I hate knowing that I only got the job because of her. I pride myself on carving my own path, and the last thing I need is a power-hungry a-hole getting in my way. Too bad my body didn’t get the memo, because the chemistry is undeniable. And my attraction to the ruthless CFO… well, it’s downright infuriating. As much as I hate to admit it, he might just be everything I never knew I needed. Even if I don’t want to. Dear reader, By His Rule is a standalone fake dating, workplace romance set in the Callahan Billionaires world.
