His Secret Babymama

Serena Vale survived Columbia on scholarships and spite, locked in brutal academic rivalry with Caspian Rothwell-the golden boy who had everything she had to fight for.
Seven years later, she has built a life as a financial analyst and single mother to six-year-old Aria, carefully constructed on the ashes of one reckless graduation night she can barely remember.
When Rothwell Industries acquires her firm and Caspian walks into her presentation with that same infuriating smirk, their old war reignites-until Aria tugs her skirt and calls her "Mommy" in front of the man who once destroyed her in every debate. Serena watches his face crack with something she can't name as he stares at her daughter, and feels the ground shift beneath her carefully controlled world.
Some battles, it turns out, were never finished-they were only waiting.
