And before Eden could wake up and face what she had done, Janice disappeared carrying the one secret that belonged to both of them. Now she is back in New York, stronger, colder, and no longer willing to lose herself for anyone again. But Eden hasn’t forgotten the woman who betrayed him, and he definitely hasn’t forgiven her. Then he meets a quiet five-year-old boy with his eyes, his heartbeat, and a smile that feels painfully familiar. Because the truth isn’t just a lie from the past anymore. It’s a child standing right in front of him.

Elena Sinclair was sixteen when her billionaire father was murdered by his own brothers, who then tried to kill her to claim his empire. Smuggled to safety and declared dead in a staged accident, she vanished into a new life as a struggling bartender—until one reckless, drunken night, on the evening she had turned 20, erased everything she’d fought to forget. She woke in the bed of Alexander Grey, the ruthless CEO of Grey enterprise and the city’s most powerful man.

Hired as his personal assistant, she must hide her identity, her children, and the truth of that unforgettable night. But Alex is no longer the stranger she escaped; he’s obsessed with the mysterious woman who vanished from his bed, and the closer he gets, the more the pieces of her past begin to unravel. As old enemies resurface to finish what they started, Elena's carefully guarded life explodes. With billion-dollar empires and two innocent heirs caught in the crossfire, she must decide whether to keep running—or trust the one man who could destroy her… or finally set her free.

For years, she lived in silence, hiding the truth, raising a secret no one could ever know. But fate has a cruel way of circling back. When the past resurfaces in the most unexpected way, everything she fought to protect hangs in the balance. The lies. The love. The billion-dollar secret. Some stories aren’t meant to stay buried. And some truths refuse to stay hidden.

“Just who is the woman behind that mask?” It’s no lie that Evangeline Laendler is one of the best con artists around. The trail of devastated moneybags who are both heartbroken and near bankruptcy because of her is enough proof. It’s all owed to her impeccable skills of switching through disguises and emanating the characteristics that her targets want to see. But this was not the life she and her dear brother had wanted for Evangeline. So when a high-priced opportunity to retire early suddenly comes, Evangeline accepts it. It was easy anyway. Seduce the billionaire heir, sway him to do terrible things so he doesn’t inherit the company, break his heart, then leave. Easy. It’s not like there was more to this guy’s story, right? What was unknown to her was just how messy and tangled this new job was, revealing secrets that even she never knew about her life. In any case, she will keep fighting to keep the facade on. Although this time, someone might just be able to unveil the real Evangeline hiding underneath.
