The Good People of Coralville — Lazette Gifford

Antoni Battista has spent his life in Chicago, shuffled from one foster home to another, causing trouble wherever he went as he grew older. After surviving a drive-by shooting in which he was in the wrong place at the wrong time, Tony's given the chance at a new start. The only catch: The small-town foster home in Coralville is one of the strictest he's ever been sent to.
If Tony can stay out of trouble for a few months, he'll graduate and turn eighteen. Circumstances seemed determined to make his vow to lay low impossible. A series of robberies takes place just after his arrival, making his new foster parents suspicious. The final blow to his plan culminates in a murder at the school. With his second chance in jeopardy, Tony sees no choice but to run...to the local sheriff.
