Book excerpt: Seventeen year-old dirt-bike-riding daredevil Arlo Santiago catches the eye of the U.S. military with his first-place ranking on a video game featuring drone warfare, and must reconcile the work they want him to do with the emotional scars he has suffered following a violent death in his family. Adios, Nirvana author Conrad Wesselhoeft, takes readers from the skies over war-torn Pakistan to the dusty arroyos of New Mexico's outback in this young adult novel about daring to live in the wake of unbearable loss.
