A bloody resistance against colonial invasion that tears Seme's indigenous leadership apart marks the entry of a strange culture into the clan. Osayo, the priest, seeks to protect the clan's religious system from erosion by the Blue-eyed (colonists). He, however, has to face off with a few loose canons, including his own son who escapes to a mission center far from home and ends up falling in love with a convert. In the meantime, a terrible plague breaks out in the clan, killing animals and people and leaving the land barren. Coupled by a misunderstanding of concepts in the new faith propagated by the Blue-eyed, a longstanding rift and blame game emerge between the converts and the conservatives, and spuns into a cutural marriage. Soon afterward, Osayo dies and his son, Okayo, realizes he has a greater role to play. The supernormal powers of the clan's aboriginal religious tree are stolen by a witch in line with a prophetic myth. And in a painful and tumultous mission to reunite the two conflicting religions of Seme Clan and limit the Blue-eyed's influence, Okayo puts his front foot forward in combating witchcraft so as to have the tree's powers in safe custody, and protect good from being superseded by evil.

My best friend, Clara Wilder, has baked an apple pie for me. But I don't hesitate to give it to my pregnant dog. That's because I've gotten reborn. In my previous lifetime, Clara had bound the Fertility Transfer System to me. If I were to eat the food she made, the baby I was pregnant with would be transferred into her womb, and she would be the one giving birth to them. Clara had married into the wealthy Gray family. For three generations, the Grays were only able to produce one heir each. That was why her in-laws desperately needed her to bear them grandchildren. Since Clara couldn't get pregnant at all, she decided to target me, her newly-wedded best friend. I went to great lengths just to get pregnant every time, but right after I ate the food Clara made, I'd go through a miscarriage by accident. Just like that, Clara was able to give birth to four sons in a row. She became the apple of her in-laws and her husband, Colton Gray's eye, which made her ego swell like mad. In the end, Clara and Colton hatched a plot where they accused me of cheating on my own husband. With my reputation flushed down the drain, I got kicked out by my in-laws. In the end, I starved to death on the streets without a penny under my name. At the end of the day, Clara wants children very badly, doesn't she? After I get reborn, I decide to give her some special "babies".

The conquest targets have fallen for the true heiress, Evelyn Swanson, who has reunited with the family at the age of 18. As long as Evelyn says something, they can easily aim their malice and hatred at me. That's why I choose to take my own life in advance. Strangely enough, everyone is filled with remorse after I die.

I suffered from severe skin hunger syndrome. Every waking moment, I wanted to cling to Charles Hansen. At night, I craved his touch even more obsessively. In Oakhaven's social circle, everyone knew me as the clingy, brainless rich wife. When I once again insisted on tagging along on Charles's business trip, a series of floating comments suddenly appeared before my eyes. [The cannon-fodder wife is at it again. She just has to follow him and ruin this client meeting too. The moment the male lead comes back, he finally files for divorce.] [She's unloved by both parents, emotionally unstable, and suffers from skin hunger syndrome. In the end, she develops depression and dies alone beneath a bridge.] [Good thing our heroine saves the deal and helps the male lead secure the client.

Then, for the first time, my arms loosened from around him.

They buried him under a blood-red moon. Chains of silver and blessed iron pinned his broken body to the earth, sealing his power, erasing his name. To the pack, he was a failed Alpha. To the coven, a cursed vampire. To the world, he was a mistake that deserved to die. But monsters don’t stay dead. When Alpha opened his eyes again, he wasn’t in the grave—he was in the body of his weakest self. Eighteen years old. Rankless. Powerless. His wolf silent. His vampire blood thin and starving. The memories of his execution burned behind his eyes like fresh wounds. Reborn. A second life… and a second chance at vengeance. This time, he felt it—the system etched into his soul, ancient and cruel. [Hybrid Core Detected] Bloodline: Vampire / Werewolf / Unknown Status: Severely Suppressed Level: 1

One life for another. That is the rule of the Aftergame. Lena was a ghostwriter who lived in the shadows—until a devastating betrayal by her sister pushed her into the path of a speeding truck.

A lethal player with eyes like cold flint, Riven breaks the game’s cardinal rule to save Lena, making them both targets of the system’s wrath.

Now, Lena is back in the land of the living, but the world is starting to pixelate. To save her, the machine that was meant to kill her has built her a cage. And in the Aftergame, mercy is the most terrifying fate of all.
