Drew was never much of a runner. Until his dad's unexpected diagnosis. Mia has nothing better to do. Until she realizes entering Half Moon Bay's half-marathon could solve her family's housing problems.

And just like that they decide to spend their entire summer training to run 13.1 miles. Drew and Mia have very different reasons for running, but these two twelve year olds have one crucial thing in common (besides sharing a birthday): Hope. For the future. For their families. And for each other.
