Unlocked

"Andy didn’t know Blake before he heard the rumor about the gun. As the janitor’s son, Andy has his own problems with nasty rumor— a commonality that paves the way for a real friendship. But when Blake starts acting strangely, Andy wonders if the gun has unlocked emotions in Blake that are more than either of them can handle. Suspecting that Blake might have a deadly plan in mind, can Andy accept that some secrets shouldn’t be kept?"
