For years, Virgil Cole and Everett Hitch have ridden roughshod over rabble-rousers and gun hands in troubled towns like Appaloosa, Resolution, and Brimstone. Now, newly appointed as territorial marshalls, they find themselves traveling by train through the Indian Territories.

When gold is discovered in the foothills just outside of Appaloosa, it sets off a fight between two shrewd local business operations as their hired gun hands square off over the claim. First a young miner disappears, then another. And then one of the businessmen himself is killed, right on his front doorstep. Meanwhile, as Cole and Hitch try to put a stop to the escalating violence, another killer is making his way toward town in pursuit of a long-lost dream and a mission of vengeance.

Sunny Randall is "on" again with Richie, the ex-husband she never stopped loving and never seemed to be able to let go, despite her discomfort with his Mafia connections. When Richie is shot and nearly killed, Sunny is dragged into the thick of his family's business as she searches for answers and tries to stave off a mob war. But as the bullets start flying in Boston's mean streets, Sunny finds herself targeted by the deranged mastermind of the plot against the Burke family, whose motive may be far more personal than she could have anticipated....

Boston P.I. Spenser is back! He's traveled west to investigate a murder in Potshot, Arizona, a former mining town reborn as a hangout for Los Angeles millionaires. A motley band of thieves, lead by The Preacher, is wreaking havoc, and Spenser must find a way to beat the gang at their own dangerous game.

Spenser is forced by loyalty into an alien world where violence is a way of lie and outsiders enter at a lethal risk. When Spenser's cohort Hawk is hired by the tenants of a gang-plagued Boston housing project known as "Double Deuce," he enlists his friend's aid. A friend's girl and her infant daughter have been gunned down. Though the act at first appears to be an accidental drive-by shooting, it soon becomes clear that it was premeditated murder.
