A high-stakes stand-alone thriller, with cut-throat family dynamics in a business empire at its core, and power a struggle that turns deadly.

The dynamics are simple in the Wolf family. They eat you if you let them.

Joe Wolf has raised three sons and one daughter using the same cut-throat mentality that built his California business empire: Kill or be killed. So when he is found murdered on his yacht adrift in San Francisco Bay, SFPD detective Ben Cantor knows exactly where to begin his investigation.

As the siblings vie for control of their father's vast power and assets, the detective pieces together the hierarchy of the 'pack of wolves'. All four have the means and the motive to commit murder.

Meanwhile, a more sinister player lurks in the shadows, one who knows the Wolfs' secrets better than Cantor ever will. And who wants them all dead.

When an unknown man is found murdered in Paradise, Jesse Stone will have his hands full finding out who he was - and what he was seeking. When a body is discovered at the lake in Paradise, Police Chief Jesse Stone is surprised to find he recognizes the murder victim - the man had been at the same AA meeting as Jesse the evening before. But otherwise, Jesse has no clue as to the man's identity. He isn't a local, nor does he have ID on him, nor does any neighboring state have a reported missing person matching the man's description. Their single lead is from a taxi company that recalls dropping off the mysterious stranger outside the gate at the mansion of one of the wealthiest families in town... Meanwhile, after Jesse survives a hail of gunfire on his home, he wonders if it could be related to the mysterious murder. When both Molly Crane and Suitcase Simpson also become targets, it's clear someone has an axe to grind against the entire Paradise Police Department.

In her latest thrilling adventure, PI Sunny Randall takes on two serpentine cases that converge into one deadly mystery. PI Sunny Randall has often relied on the help of her best friend Spike in times of need. When Spike's restaurant is taken over under a predatory loan agreement, Sunny has a chance to return the favor. She begins digging into the life of the hedge fund manager who screwed Spike over - surely a guy that smarmy has a skeleton or two in his closet - and soon finds this new enemy may have the backing of even badder criminals. At the same time, Sunny's cop contact Lee Farrell asks her to intervene with his niece, a college student who reported being the victim of a crime but seems to know more than she's telling police. As the uncooperative young woman becomes outright hostile, Sunny runs up against a wall that she's only more determined to scale. Then, what appear to be two disparate cases are united by a common factor, and the picture becomes even more muddled. But one thing is clear: Sunny has been poking a hornet's nest from two sides, and all hell is about to break loose.

Robert B. Parker's iconic and irresistible PI Sunny Randall is back, and the stakes are higher than ever as she races to protect her ex-husband-and his Mafia family-from the vengeful plan of a mysterious rival. Sunny Randall is 'on' again with Richie Burke, 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 Richie's family, whose motive may be far more personal than she could have anticipated...

Robert B. Parker's beloved PI Sunny Randall returns on a case that blurs the line between friend and foe... and if Sunny can't tell the difference, the consequences may be deadly. When Sunny's long-time gangster associate Tony Marcus comes to her for help, Sunny is surprised - after all, she double-crossed him on a recent deal, and their relationship is on shakier ground than ever. But the way Tony figures it, Sunny owes him, and she is willing to consider his case if it will clear the slate. Tony's trusted girlfriend and business partner has vanished, appearing to have left in a hurry, and he has no idea why. He just wants to talk to her, he says. While Sunny isn't willing to trust his good intentions, the missing woman intrigues her - against all odds, she's risen to a position of power in Tony's criminal enterprise. Sunny can't help but admire her and, if this woman's in a jam, she would like to help. But when a witness is murdered hours after speaking to Sunny, it's clear there's more at stake than just Tony's love life. Someone - maybe even Tony himself - doesn't want this woman on the loose...and will go to any lengths to make sure she stays silent.

When two seemingly unconnected mysterious deaths occur on his watch, police chief Jesse Stone must pull out all the stops to unravel the truth and stop a killer from striking again. The small town of Paradise is devastated when a star high-school baseball player is found dead at the bottom of a bluff just a day after winning the team's biggest game. For Jesse, the loss is doubly difficult - the teen was the nephew of his colleague, Suitcase Simpson, and Jesse had been coaching the young shortstop. As he searches for answers about how the boy died and why, he is stonewalled at every turn, and it seems that someone is determined to keep him from digging further. Jesse suddenly must divide his attention between two cases after the shocking murder of former Paradise police chief, Charlie Farrell. Before his death, Farrell had been looking into a series of scam calls that preyed upon the elderly. But how do these 'ghost calls' connect to his murder? When threats - and gunshots - appear on Jesse's own doorstep, the race to find answers is on. Both old and new enemies come into play, and in the end, Jesse and his team must discover the common factor between the two deaths in order to prevent a third.
