The Undercover Omega

"Seven days... that's all it will take before she breaks and quits!"
That was the absolute guarantee of 'Rayna Lertwarasakul,' the dictatorial Alpha CEO who had already ruthlessly churned through twenty-eight secretaries. But the twenty-ninth, 'Linlada,' was a different breed entirely. Whether it was demanding revisions at 2:00 AM, upending the schedule at a moment's notice, or hurling icy tantrums, Linlada handled it all with a serene 'smile' and a cup of espresso brewed to an infuriatingly perfect seventy-five degrees.
Initially hell-bent on forcing her to resign, the tyrannical Alpha found herself unwittingly addicted to her sweet-faced secretary's presence. The boss who once scrutinized her every flaw transformed into a fiercely 'possessive' predator, drawing the whispered attention of the entire corporate tower.
But little did the CEO know... the Omega she was falling desperately in love with was actually the sole heir to the majority shareholder, infiltrating her ranks to unearth a traitor from within!
When love sparks from the ashes of hostility, divided by a billion-dollar secret... what will the arrogant, untouchable boss do when she realizes she can no longer fire this woman from her 'heart'?
