   Summary

   Agatha Harkness runs an underground service where she seduces and humiliates arrogant Alphas on behalf of wronged omegas, taking pride in dismantling their disgusting egos. After completing another successful job, her friend Lilia asks her for an unusual favour- helping her shy, underconfident Alpha niece learn to step into her identity. Reluctantly agreeing out of loyalty (and of course payment), Agatha is introduced to Rio, a sweet, unsuspecting Alpha who is nothing like the alphas she’s used to tearing down.
