What Is The Twist Ending In 'The Good Sister'?

Arwen was never supposed to be here. Her sister was the beautiful and confident one.
The one promised to billionaire tycoon Caelum Ravencroft. But days before her wedding to billionaire CEO Caelum Ravencroft, the perfect Isolde disappears. To save their family from ruin, her quiet, overlooked sister Arwen is pushed into her place. Caelum is powerful, distant, and used to getting exactly what he wants. He expects a polished bride who fits his world. What he gets instead is Arwen-quiet, thoughtful, an artist who hides her dreams and her pain behind polite smiles. He doesn’t trust her. She doesn’t trust him. But living under the same roof, pretending to be husband and wife, cracks something open neither of them planned. Then a message shatters everything: Don’t trust her. When Arwen’s secret is exposed, she’s thrown out with nothing but heartbreak — and a truth that could change everything. Because while Caelum believed she was lying to him, he never saw the real danger closing in. Now his enemies are circling and his empire is burning. The only woman who can save him is the one he lost. But… She’s already gone. And she’s carrying his heir.

“She has twelve weeks to live. And she's running out of time to get revenge for her sister.” Alexa Lean grew up with only one person in her corner…her fraternal twin, Alice. Orphans. Outcasts. Each other's entire world. So when Alice is found dead in a campus lake, ruled as murder, Alexa doesn't mourn. She moved to Westbrook University. She enrolls as a transfer student. And she begins hunting the killer. But someone is watching. A break-in. A photograph of Alice's dead body. A whispered warning in the dark: "Stop asking questions." The deeper Alexa digs, the more she uncovers. A web of lies that has been strangling Alice since childhood. Then there's Myles Clay. Alice's boyfriend. Grieving. Gentle. Dangerous in ways neither of them expected. He should be a suspect. Instead, he becomes something worse: the only person Alexa can trust. As her body begins to fail and the killer closes in, Alexa must solve her sister's murder before the her illness solves her. But the truth is closer than she thinks. The killer has been watching her all along. And they're not done killing. Will Alexa’s sickness make her weaker or stronger in her journey to get revenge? Or will it be the only thing to build her?

As the youngest daughter of the Costellos, I had always lived in my sister’s shadow. That was until five years ago, when she betrayed the family and ran off with a street thug. I took her place and completed the wedding with Elio Ross. Over the years, he loved and indulged me, but we never got a marriage license. He always said family matters kept him busy, and that, with or without it, I was his wife in his and the family’s eyes. I believed him. Until today… I watched as Elio walked out of the church with my sister Alyssa, who had been missing for five years, both of them wearing the family rings that symbolized their union. At the church entrance, three black SUVs opened their doors simultaneously, and my three brothers stepped out in tailored suits. “The ceremony’s done? We’ve already booked Antonio’s to celebrate Alyssa’s return.” They climbed into the cars, expressing their joy, while no one noticed my pale, shattered face across the street. Later that night, under the guise of apology, my sister let a venomous spider bite me. “A substitute is always a substitute. Now that I’m back, it’s time for you to die.” I screamed for help. However, my husband and my three brothers only rushed to hold my sister, who had pretended she had fallen, without a glance at me, writhing from the poison. They called in every specialist from the hospital, only to tend to my sister’s scraped knee. That was the moment my heart truly broke. After being dragged back from death’s door by the doctors, I made my decision. I picked up the phone and called the International Private Island Exchange. “That isolated, uninhabited island… I’ll take it.”
