You'll Be The Death Of Me, Karen M McManus

 Ivy, Mateo and Cal used to be close - best friends back in middle school. Now all they have in common is a bad day.

So for old time's sake they skip school together - one last time. But when the trio spot Brian 'Boney' Mahoney ditching class too, they follow him - right into a murder scene. They all have a connection to the victim.

And they're ALL hiding something. When their day of freedom turns deadly, it's only a matter of time before the truth comes out . . .
