Acclaimed author David Joy returns with a fierce and tender tale of a father, an addict, a lawman and the explosive events that come to unite them.

When his addict son gets in deep with his dealer, it takes everything Raymond Mathis has to bail him out of trouble one last time. Frustrated by the slow pace and limitations of the law, Raymond decides to take matters into his own hands.

After a workplace accident left him out of a job and in pain, Denny Rattler has spent years chasing his next high. He supports his habit through careful theft, following strict rules that keep him under the radar and out of jail. But when faced with opportunities too easy to resist, Denny makes two choices that change everything.

For months, the DEA has been chasing the drug supply in the mountains to no avail, when a lead ? just one word ? sets one agent on a path to crack the case open... but he'll need help from the most unexpected quarter.

As chance brings together these men from different sides of a relentless epidemic, each may come to find that his opportunity for redemption lies with the others.
