What They Always Tell Us — Martin Wilson

JAMES AND ALEX have barely anything in common anymore--least of all their experiences in high school, where James is a popular senior and Alex is suddenly an outcast. But at home, there is Henry, the precocious 10-year-old across the street, who eagerly befriends them both. And when Alex takes up running, there is James's friend Nathen, who unites the brothers in moving and unexpected ways.
