Knot Their Only Omega by Erin Mersey

Violet doesn’t have a choice.
Omegas like her never do.
Sold to an Alpha who used her and called her broken, she’s spent two years in silence, until spring arrives and a forced heat sends her running for her life.

Her escape ends in the arms of Serena and Vinny, two alphas who smell like fresh beginnings and everything she’s never had. With them, Violet discovers a life she never knew existed, and the fragile hope that she might finally bloom after a long, brutal winter.

But spring doesn’t erase the past.
Her old alpha wants her back, and he wants the heir he was never able to force from her. Too bad her new alphas won’t let go of what’s theirs.

Knot Their Only Omega is an interconnected why-choose omegaverse standalone about a runaway omega, found family, and the courage to grow in the light after surviving the dark. Both MM and FF pairings appear on-page.
