Sonja Underworld Novels & Stories

Two alpha males. One forbidden siren. A bond that breaks every rule. Althea Lake has always known she was dangerous. As a siren, her beauty and voice were crafted by nature to lure powerful mates—and in a world ruled by dominance and legacy, sirens are both coveted and feared. Desired by kings, claimed by titans, and whispered about in secret, they are walking temptation. But Althea isn’t hunting for power. She’s hiding from it. That is, until fate brings her face-to-face with the two most dangerous—and unclaimed—males in the supernatural world. Cassian Morningstar, the Demon King of the underworld and a cold-blooded CEO by day, built his empire with ruthless control. Xanden Moon, a deadly fae warrior and Cassian’s co-ruler, is known for his loyalty, precision, and barely leashed violence. Neither has ever found their fated mate. Until her. Althea is theirs. The bond is undeniable. But a siren having two mates? Unheard of. Forbidden. And potentially catastrophic for the balance of power in their world. Torn between her fear of being claimed and the impossible heat pulling them together, Althea must decide whether to resist her nature—or surrender to a destiny that could consume them all. In a world of magic, power, and primal instincts… some rules were made to be broken.

After her father’s death leaves behind nothing but a ten-million-euro blood debt, Graziella is dragged into the world of the Vitale brothers, men who rule the city’s underworld with violence, power, and a loyalty that has no room for mercy, and who, by law and history, are also her stepbrothers. In their hands, debt is not something to be repaid but something to be owned, and because her father failed them, Graziella becomes the collateral they inherit, allowed to exist only as long as she remains useful and silent. For months, she survives by making herself small, enduring cruelty and indifference alike, learning that in a house built on fear, silence is not submission but survival. To the Vitale brothers, she is temporary, a problem that will eventually disappear once its value is exhausted. Everything changes when the eldest announces his political marriage, a union meant to secure alliances and erase liabilities, and Graziella realizes how easily she will be discarded. Instead of begging, she makes a single request: thirty days as their wife and queen, not as property but as a recognized presence, after which she will vanish forever. They believe she is desperate. They believe she wants protection or love. What they fail to see is that Graziella is not bargaining for affection, but for access. Because in those thirty days, she watches, listens, and learns, and by the time they understand what she has become, the quiet debt they ignored will be ready to rule them all.
