Every serial killer needs a friend. Every game must have a winner.

When a chance meeting sparks an unlikely bond between rival assassins Sloane and Rowan, the two forge something elusive - the friendship of like-minded, pitch-black souls. From small town West Virginia to secular California, from downtown Boston to rural Texas, two hunters meet in an annual game of blood and suffering that pits the most dangerous monsters in the country against each other.

But their friendship gradually grows into something more, and the restless scoundrels are just a few steps behind, ready to seize something more than their newfound love.

Can Rowan and Sloane escape their deadly games of chance? Or will they both finally realize that they are perfect for each other?
