Charming by Eve R. Hart

Charming:
I cared about her more than I should have. Abigail. Dade’s little sister and sweetest woman I’d ever known. But it was that first part that held me back. When I finally got the courage to man up, life threw another curveball.
All it took was one thing to snap me out of it.
One stupid kiss to one of my brothers who was also my best friend.
So, I told her everything— well, almost everything.
She wasn’t shy about her curiosity and knowing that Blade cared about her just as much as I did, I figured why make her choose when we could give her everything?

Abigail:
I could admit that I often got crushes on the club members. It never mattered though because they all saw me as a little sister.
Life got turned upside down in the blink of an eye and suddenly, I had two big protectors that watched me from the background. They were always there but in different ways. One was sweet and comforting. The other was silent and strong.
They didn’t ask me to choose, so why would I?
But then I learned the truth of what they’d been hiding from me and I didn’t think I’d ever be able to trust the club again.
