She's the roller derby captain and her newest rival is her very own teammate.

There are only three things that get under Madeline Maddox's skin: defeat, disorder, and disruption, especially when it comes to her carefully curated life and her roller derby team. Because no one outskates Mad Maddox-that is, until a cocky little jammer blows back into her hometown wreaking havoc into all her plans.

Vera Havik is mayhem, she's chaos, she's everything Madeline despises.

Madeline is set on making their time on the track together a rink-rash-filled nightmare, pushing through Vera's defenses like a bad block. That's when she learns the heavy secret the world-famous jammer is hiding. Everything's off-track now, including their hearts.

The fine line between love and hatred can be crushed, snorted, or injected...

But it can't be ignored.
