What's worse than getting roped into profiling a killer? Being forced to work with a woman who disrupts my perfectly controlled world.

That was me. Dominic Barrett. That was my mistake. I let her in.

Dr. Claudia Marlowe is all sunshine and confidence, the kind of woman who lights up a room just by walking into it. Too bad I prefer the dark.

I'm a Harvard neurochemistry grad student with a restless mind, a motorcycle that outruns my demons, and a long list of vices to keep me sane. I don't do warmth. I don't do easy. And I sure as hell don't do people like her—bright, untouchable, everything I can't afford to want.

She thinks we're just research partners. Thinks I'll play nice, help her profile a murderer, and then go back to my carefully constructed life.

She's wrong.

The closer we get, the harder it is to stay away. She's a dangerous variable in my perfect equation—unpredictable, chaotic, impossible to resist.

And the real problem? I don't want to resist her at all.

Pinned Throttle is a steamy, grumpy-sunshine, reverse age gap biker romance featuring a brooding neurochemistry grad student, a brilliant criminologist, and a collision neither of them saw coming. Book two in The Bikers of Boston Series is a connected standalone.
