Chasing Wild Heart by Chessa Andersen

Juniper Mitchell:
The new assistant cross country coach, Dash, irritates me. His training methods are surprisingly helpful, but his overzealous determination to win is annoying as his name and handsome face. Whatever happened to “go do your best but have fun”? Because hearing “your best isn’t good enough” is a little more than irritating.
The more he pushes, I push back twice as hard with a few choice words and an intimidating stink eye.

Dashwood Black:
Juni irritates me. She’s the epitome of a team player, pushing others to dig deep and watching them shine while she stands contently in their shadows. She’s outgoing, sassy, witty, and refuses to listen to a helpful word I say as an assistant coach.
While the team itself boasts solid rankings in the division, I know for a fact Juni’s name would be at the top in the individual rankings. The fact she’s not even considered the team’s number one runner puzzles me, but her lack of drive to push herself irritates me even more.
When I chase her for answers, she challenges me to examine my own past and the one rule I followed most my life. Maybe winning isn’t everything. Or even the only thing.
