Outcasts: All good things... (The Outlaw Series) (Volume 4)

All Good Things...
...must come to an end.

A showdown looms between monsters.
Villain versus vigilante.
Chemist versus Outlaw.

Time grows short. Old enemies and new gather for the reckoning, a battle which sprawls across Los Angeles. Forced from their families by discovery and betrayal, Chase and Katie are cast into danger while the Infected take sides and rip at the fabric of order and chaos. America groans under the weight of a madman, and teeters on the precipice of war.

To win, the Outlaw must decide how much he's willing to risk. And who he's willing to risk. 
Because some battles can't be won by strength alone.
And some battles can't be won at all.
