Hangman's Knot

Eden North was doing perfectly fine on her own, thank you very much. She completed her two-year childhood education degree, got a job as a teacher’s assistant, and was keeping the plants in her apartment healthy and thriving. It wasn’t easy as an unbonded omega with no family, but she wasn’t interested in alphas or bonds. The pickings out there are slim and she’s better off alone.
That is, until she gets caught up in a human trafficking conspiracy and she finds herself thrown in a private men’s prison in a campaign to calm the alpha populations. Unbonded omegas with no family or mates are nothing more than prey for the taking, and a female omega in a prison full of violent alphas is nothing more than meat in the grinder.
Until Luke, Julius, and Tenor step in to keep her from being attacked on her first day in the prison. They protect her, soothe her, and claim her as their own. But when her heat spikes with potent omega pheromones, Eden finds herself wondering whether these three powerful alphas might be more than just her protectors.

They might be her mates.
