Knox Mercer has lived his life by one rule: family first, mercy last. When his brother Colt is gunned down, Knox swears blood for blood. But the trail of smoke leads to the one woman he can't forget- Nova: the ex-lover who once burned his heart and just might have pulled the trigger. Nova escaped a monster, but she can't outrun the past-or the man who still owns her heart. Now Knox has a gun in his hand, a flash drive full of secrets, and a choice that will ruin them both. Love. Lies. Brotherhood. Revenge. When the final shot rings out, who will walk away-and who deserves mercy?
