A new world with nearly unlimited possibilities. A system, classes, magic, skills and monsters. Sounds exciting? But for Jin it didn't go quite as he expected nor was there a princess or a Goddess to welcome him to this new world, his only hope was the system he received. Left alone in the darkness, How will he survive when he wasn't human in the first place?

In the new world order, humans are nothing but property. Omegas, wolves, and rogues rank higher, leaving humans powerless, destined for collar and chain. She grows up knowing this, but hopes for mercy when her turn comes—a gentle Alpha, a kind Luna, someone who will put her to work but leave her body her own. On the night of her auction, hope dies. She is purchased by Caelan Black, Alpha of the feared Ironfang Pack. Cold, violent, and legendary for his cruelty, Caelan doesn’t buy humans for labor—he buys them for heirs. From the first night, he makes it clear: she is not his mate. She is not his Luna. She is his breeding pet—a body to keep in his bed until she bears his pups. Collared and caged, she fights him, refusing to bend. But Caelan is patient in his cruelty, teaching her submission with hands, mouth, and punishing nights that leave her trembling yet craving more. Soon, her body betrays her. Desire coils through her veins, and in his eyes, she begins to see something more dangerous than lust—possession. When rival Alphas discover Caelan has bonded with a human, they see weakness. They come for her, threatening to steal his breeder and expose him as unfit to rule. Blood is spilled, war ignites, and in the chaos, she realizes the truth: she is no longer just his pet. She is his obsession, his weakness, his ruin. And when the Goddess herself tests their bond, she must decide—remain the breeder he bought her as… or claim her place as the Luna he swore she could never be.

In a world that has long considered werewolves a myth, old blood is stirred again when Raven—an ordinary young man living on the brink of collapse—is suddenly chosen by something that shouldn't exist. A mysterious system emerges within him: the Werewolf Evolution System. At first, Raven thinks it's just a delusion... until the first night of the moon changes. His bones crack, his blood boils, and something inside him begins to "awaken." But the transformation isn't just a curse. It's the beginning of evolution. Every battle he wins, every enemy he defeats, and every drop of blood he sheds, the system evolves, giving him new abilities, new forms... and a dark side that's increasingly difficult to control. Behind it all, the world begins to stir. The secret government, werewolf hunters, and the Alphas of various packs begin to sense something unnatural—a werewolf who defies the rules of natural evolution. Because Raven isn't just a human who became a werewolf. He's an anomaly. And when the final “evolution path” opens, Raven will be forced to choose: Become king among monsters… Or lose herself completely and become a disaster that even the Alphas can't stop. But one big question remains: Who really created the Werewolf Evolution System—and what is Raven's true purpose?

In shifter society, Eden isn’t the paradise you’re used to hearing about in the Bible. It’s the place where all girls are housed from birth until their 18th birthday. A war between the humans and shifters left the werewolf population decimated and diseased due to poisonous agents used against the wolves. As a result, birth rates of purebred werewolves declined extraordinarily, while the presence of mutant werewolves rose. To combat their fertility crisis, the Elders invented Eden where young girls were kept locked away from society. Their knowledge of the outside world is very limited and their only purpose is to become breeders after their 18th birthday when they are selected by their mates during the Breeding Selection Ceremony. If the girls don’t prove they are purebred wolves or turn into mutants, then they are killed by the Alphas. Imani is shamelessly classified as a Breeder C–the most undesirable amongst the breeders. She hates that the girls are subjected to such barbaric practices and desires to escape from Eden. What she doesn’t expect is to run into Alpha Jackson, the man who was tasked to kill her on her 18th birthday if she didn’t prove to be a purebred wolf.  The Breeding Selection Ceremony commences and Imani is certain she doesn’t have a wolf. As her “sisters” are dying around her, Imani is shocked when Alpha Jackson spares her life. Not only does he spare her life, but he selects her as his Breeder! Alpha Jackson only kills when he’s 100% certain, but there is something off about Imani and the only way he can get to the bottom of it is if he keeps her close.

The city was a cage. The forest is a hunt. Lila Voss ran to the decaying town of Eldridge Hollow to disappear. Broken by the suffocating expectations of her old life, she wanted nothing more than to be invisible. But when she cuts through a rain-slicked alley on her first night, she learns that some things cannot be outrun. She is found by Jax—a massive, feral Alpha wolf shifter who has been tracking her scent. He doesn't offer help; he offers a claim. Driven by a primal biological imperative, Jax bites her, kidnapping her into the depths of the forest to face a destiny she never chose. Now, Lila is no longer human, but she isn’t yet a wolf. Trapped in the pack’s subterranean den, she must survive the agonizing, bone-breaking transformation into a rare Silver Wolf. But her survival isn't just about the shift. Thorne, a sadistic rival Alpha, covets Lila as a trophy to breed a stronger bloodline, and he’s willing to burn the forest down to take her. With a war brewing on the border and a scorching, undeniable bond consuming her from the inside out, Lila must decide: will she remain the victim, or will she embrace the monster within and become the Queen the pack needs?
