From the back of the book:

"If Michaela is going to run cross country, she needs to learn how to be part of a team.

Michaela is kind of a loner.  As a sprinter, this suits her just fine, since it's just her versus all the other runners on the track.  Her one attempt at cross country running as part of a team at summer camp is a dismal failure - one her teammates don't let her forget!

But when the new school year starts up in the fall, Michaela finds herself alone at school for the first time since her best friend moved away.  Determined to make friends and fit in, she decides to give cross country another try.  At least it's running, and Michaela is good at that!  But does she have what it takes to be part of a team?"

From Amazon:

"Set in a diverse neighbourhood in Scarborough, Ontario, this book follows Michaela as she goes from a solitary runner to an athlete who contributes to the success of her cross-country team. Discouraged by an incident at her mostly-white summer camp, Michaela comes into her own as part of her racially diverse school track team. Focusing on themes of persistence, friendship and overcoming rivalries, this book illuminates traits of connection, empathy and forgiveness."
