Toxic Biker by Sapphire Knight

I was never supposed to fall for her. She’s forbidden, my best friend’s little sister. She came to me for help and I couldn’t turn her away.

I’m not supposed to have her, to touch her, or love her. I’m toxic, I always have been. People leave me one way or the other, they never stick around and it’s turned my heart black. I refuse to get too close to her, but when she cries, begging me to find her missing brother, I can’t say no.
I’ve stayed away for years, making the club my life. They’re my brothers, the ones who never leave and always have my back. She’s not from my new world, she doesn’t fit, but I don’t want her to.

She’s my weakness. The woman I’d do anything for and when she’s threatened, I learn there are no limits. She’s mine to protect, to touch, and keep forever.
No one will ever claim her… except me.
