This is a short novella type book that honestly is mostly s*x and nonconsensual at that.
Slight spoliers ahead:
Our FMC, Karissa, is celebrating a friends birthday at a club where she is given a drug that seems to induce her change into an omega without her realizing. She stumbles out of club trying to get home when she is spotted by the pack and consequently is claimed by the pack of 7 men without her verbalizing consent. She wakes up and is again persuaded by alpha purrs and instinct to solidify the claim after verbalizing that this is not what she wants and would like to go home. But of course the alphas don’t listen and continue to tell her what she needs.
