Excerpt from In George’s Shoes Natalie Stewart

Owen kicked dirt beyond home plate, sending cloudy powder into the humid summer air. He scowled and pouted. He exhaled up at the sweat that trickled down his forehead as he hoisted the densely packed satchel from the ground. His baseball team, the Trail Blazers, had just won yet another series game; Owen, however, was feeling irritated.

He observed his teammates surrounding George, who had driven in the winning run. George was the team’s finest hitter, and the other players cheered, clapped, and high-fived him. The victory elated them.
