Still mourning the loss of Lucas Nelson, the boy she loved in secret for years, seventeen-year-old Emmy Martin turns to her passion for mountain biking to try to fill the empty void in her life. But just when things start looking up, Emmy discovers her mom has been diagnosed with early-onset Alzheimer’s. Confused and angry, she throws herself into mountain biking like never before. She wants to improve on the trails, get a sponsor, and finally beat her nemesis, Whitney.

When Cole Evans, a boy from school who usually doesn’t care about anything but himself, offers to train her for the biggest race of the season, she accepts, determined to beat Whitney. The more time she spends with Cole, the more she realizes he’s different than she’d expected, and, to her surprise, she’s falling for him. Torn between the deep feelings she still has for Lucas and her growing ones for Cole, she knows she must choose a path.

As she drifts further away from her family and closer to her dream of being sponsored, a terrible accident threatens any semblance of peace and happiness she has left. Instead of closing herself off to the people she loves, Emmy must learn to rely on those she has pushed away if she’s going to have any chance of picking up where she left off before the accident.
