Army by Chiah Wilder

A sizzling and gripping story of forbidden lovers caught in the crossfire of vengeance.
A member of the Night Rebels MC, Army is an arrogant, tough SOB, and he makes no bones about it. His idea of having a good time is riding his Harley, boozing with his brothers, and having rowdy sex whenever the mood strikes him–which is often. Hook ups are on his terms, and if a woman doesn’t like it, there’s always another one waiting to take her place.
Then he sees her fighting in the ring, moving in ways that give him a whole bunch of nasty ideas about what he wants to do to her. And the way she looks at him? Well … there’s no denying the intense, mutual attraction. Chemistry sparks between them like the Fourth of July.

The only problem? She says she’s not interested. What the …?
Stiletto’s attraction to the rugged biker is like a storm electrifying the air, but with his swagger and perpetual smirk, he’s a poster boy for shattering hearts. If only her body would understand that.
Then she finds out he’s a member of the Night Rebels Motorcycle Club and is a deadly rival of her brother’s motorcycle club–The Satan’s Pistons.
But one night with him wouldn’t hurt anyone.
It’d just be a hookup, and probably the best sex she’d ever had.
Besides, who would ever know?
