Why Does Sister Rivalry Turned Deadly Fascinate Audiences?

“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?

Lucinda was hiding a great secret from Lily before her death and now, Lily is harbouring a terrible secret about Lucinda's death from everyone. As the story unfolds, the truth about Lucinda's alcoholism and death comes to light.

My brother was a twisted, paranoid psychopath. When I was ten, my parents were murdered. Both my legs broke off while I tried to save my brother. I became his only family and also Achilles’ heel. Those who mocked me as a crippled would have their bones broken, and anyone who tried to hurt me would be smashed into a pulp. As he reclaimed our family’s fortune, he became “the Devil” in Amberwater, a man no one dared to offend. Yet, he alone spoiled me like I was a little princess. Everyone knew that Lucas’s sister was untouchable. He had sent me abroad to receive the best treatment. The day that I could finally stand up again, I received an invitation to my brother’s engagement banquet. “Veronica, we’re going to have a new family member soon.” I heard that his fiancee was the daughter of a wealthy family. She was gentle and virtuous. I dressed beautifully to meet her and planned to give her the jade bracelet that my mother had left behind. However, she had me kidnapped and taken to an abandoned construction building. “You lowly little witch. I’ll rip that face of yours since you’re such a seductress. I’ll see how you’ll steal my man now!” She crushed my mother’s heirloom, broke all my limbs, and ripped my face off. Then, she ordered a dozen men to torment me to death. In the end, she stuffed me into a gift box and sent it to my brother. “Dearest, this is your wedding gift. Do you like it?”

Like me, it seemed my younger sister was reborn. In our past life, she was obsessed with the golden boy of the elite circle. She would ditch classes, get into fights, and race through the streets at night all for him. In the end, she died for him in a storm and blamed me for all of it. After her rebirth, she manipulated our parents into transferring me to his class, notorious for being the worst in school. "Sis, this time, it’s your turn to get bullied by him. To fall for him. To suffer like I did." I just smiled. Coming back to life didn’t make her any smarter. Even if she lived a hundred lifetimes, she would never be a match for me.

My older sister was always kind-hearted, while I was born a natural troublemaker. When the intense heatwave struck, our family stocked up on supplies and stayed indoors. My sister saw a little boy, who seemed about seven or eight years old, crying and asking for help. She decided to take him in. “We’ve plenty of supplies anyway. One more person won’t make much difference. Besides, he’s just a child.” I warned her that the boy looked oddly mature and might not be as innocent as he seemed. I suggested we observe him a bit longer. She said I was a cold-hearted troublemaker by nature. Then, she went and let him in anyway. Not just that, but she also convinced our mother to force me to share a room with the boy. That night, the scheming “little boy” secretly climbed into my bed. I was brutally assaulted. Yet my sister told me to let bygones be bygones and marry him. To force me to obey, she locked me out on the balcony at over 140 °F. Enraged, I set a fire and killed everyone. When I opened my eyes again and saw my sister safe and unharmed, I smiled. This time, I would show them what a troublemaker really was.

My sister pulled a knife during a robbery attempt, and we got into a brutal fight. My mom, an auxiliary police officer, arrived at the scene but totally ignored my injury. As I lay in a pool of blood, begging for help, she just cradled my sister and yelled at me, "You're so desperate for attention that you'd hurt your sister? How did I raise a heartless monster like you?" She branded me as the aggressor, ignored my pleas, and rushed my sister, who had mere scratches, to the hospital. I was left alone to die miserably in that deserted alley. When the news of my death arrived, my mother dismissed it as another one of my lies, pointing at my body and demanding I get up to apologize to my sister.
