Partners in Crime (Carl Gallagher Book One of the Ride or Die Series)

On the Northside or any place nicer then Southside Chicago love was something pretty it was flowers and chocolate and kindness. Not on the Southside though, not in the places were god had left. Here love is finding the person who will ride with you and die with you who will kill for you and bleed and fight and lie to the cops. You want to love on the Southside, you have to be willing to fight to the death for it because nothing comes easy here.

Hailey Ball and Carl Gallagher meet when they're still kids after the abandonment of Hailey's parents, they bond over the deadbeats in their life and the destruction of anything they can get their hands on. They don't realise what they have until it's nearly too late but once they do neither one of them will be going down quietly or without a fight.
