I only realized I was the protagonist of a mafia novel after I met my husband, and the mafia boss, Lucien Vaughn, was a traveler from another world. According to the rules of his world, he wasn't allowed to develop romantic feelings for anyone in the story. However, the moment he saw me, he fell in love. And every time his heart stirred for me, he suffered pain so intense it felt as if his soul were being torn apart. He endured it ninety-nine times. Then, one day, I was kidnapped by a rival mafia family and taken to South Merica, where I suffered brutal torture. Yet somehow, I managed to escape and hide in a basement. As I listened to my enemies raging outside and searching for me, I quickly used the secret method Lucien had taught me to contact the world beyond this one. The connection worked, and through it, I overheard a conversation between Lucien and one of his friends from the other world. “Lucien, I thought Olivia was the person you loved most! How could you arrange for your enemies to kidnap her?” Lucien's voice was calm and detached. “I didn't have a choice. If I hadn't done it, then Emily Carter would've suffered in this storyline instead. She’s only a supporting character. She would’ve died. “But Olivia is the protagonist. The storyline will protect her. Once this story’s mission is completed, I'll finally be able to stay in this world forever. And when that happens, I'll make it up to Olivia." Tears streamed down my face. My heart felt as if it had been ripped apart, leaving behind nothing but pain and despair. So, when my enemies finally smashed open the basement door, I didn't struggle or run.

Leaving your world and coming to another all seems wrong and right. Sophia had to leave Marazona to Earth to avoid death in the most cruel way. Everything on Earth seemed weird to her and she seemed weird to Donald, the son of the woman that took her in. But, let's see how Two Worlds are Connected.

The world ended in 2015. Sheng Chen was transported to a new realm along with the rest of humanity. The novel follows his adventures through this vast new plane, fighting men and beasts alike, making friends, finding love, and etching out his own existence in the boundless universe all the while trying to unravel an insidious plot that he has unwittingly become a part of. Romance, humor, friendship, betrayal, loss, schemes, light, and darkness. All the creatures from your dreams, stories, and movies are real in this absurdly wonderous world.

Six years after I allegedly crossed into this world, Liam Locke slid a ring onto my middle finger and suddenly tightened his grip on my hand. "Keira, the whole parallel world story isn't real." He lowered his voice. "It was just an excuse so I could be with two people at once." I went still. He even winked at me, like this was all in good fun. "I never had a childhood sweetheart. Demi's the woman I cheated with. "The day you showed up at the hotel, I made that story up on the spot. You believed it. You actually thought you were the one who didn't belong here and waited for me for six years." My chest clenched tight as I stared at his face in shock. "Then why are you proposing now?" "Call it mercy. We've been together almost eight years." He smiled. "Once Demi goes overseas to study, I'll give you your old life back. What do you say?" I looked at the girl in the distance, the one who had spent the past six years living openly as Liam's real girlfriend. A heavy exhaustion settled over me. He didn't know this, but I had actually come from another world. A world without him.
