"You can't reject a mate bond on your own, Siren. It takes two." "Stop calling me that!" "I prefer it." "This is bonkers. We're step-siblings!" "Not blood. Our parents got married. That doesn't make us related." When twenty-year-old omega Soren moves into her mother's new husband's mansion, the last thing she expects is to discover that her arrogant new stepbrother, Felix, is actually her fated mate. Forced to live under the same roof and attend the same college, Soren and Felix try to ignore the powerful attraction between them. But the mate bond refuses to be ignored, pulling them closer with every stolen glance and every secret encounter. Then Soren learns the truth: Felix has been betrothed to another woman for years, a political marriage meant to secure the future of his pack. With the wedding approaching and their families only one discovery away from tearing them apart, their forbidden relationship becomes a dangerous secret. As tension grows, Felix's reckless biker cousin Kai steps in, determined to expose their bond or claim Soren himself. Now Soren is trapped between duty, desire, and a love that could destroy both their families. Because in a world where alphas don't mate omegas and step-siblings should never fall in love, their connection isn't just forbidden, it's explosive. When the truth finally comes out, will Felix fight for their impossible bond or will Soren lose the one man fate chose for her?
