Sierra Cody is on fire. A rising star in women's professional downhill mountain bike racing, she has all the tools to become a world champion. All she needs to do is fully commit herself. Something far easier said than done.

Dr. Kara Davies, a highly regarded and accomplished physician, is well on her way to achieving her dreams in chiropractic research. Commitment to her goals has never been an issue, but her personal life is a different story. Preferring the comfort and safety of her lab over personal relationships, Kara's one-track mind allows no deviation.

But life is full of twists and turns.

After an accident on the track lands Sierra in Kara's on-site medical center, the doctor suddenly finds she has more on her mind that work. Blindsided by mutual attraction, Sierra and Kara struggle to accept their feelings for each other and to deal with the change it brings.

Will love be enough? Or will life's little switchbacks send them both careening off course?
