Switch Heater by K.L. Moore

https://amzn.to/43d8RUL

Three years. Three years at the Omega Center, learning everything I need to learn, becoming the omega that they say we’re supposed to be. You know what else they say? That we’ll find our pack, our alphas, while here. There hasn’t been an omega yet that’s walked through those doors and not walked out ready to bond with their intended packs and alphas. The exception being me. I haven’t found my pack.

On my last night at the Center, however, I catch a scent that nearly drives me crazy. I found them there. Syn and Kian. And that scent around them that makes my knees weak? It belongs to their omega.

*Switch Heater is a polyamorous omegaverse romance. There are FF/MM situations throughout the entire book.
