A majestic wolf prowls the halls of power, protecting his pack of shape-shifters from those who would harm them.

But a wolf is not meant to hunt alone…

Nick Carter hides his wildness under expensive suits, but nothing can lessen the impact of what he is: alpha wolf. He leads his region's Sentinels, a duty he takes seriously. He is cautious, ready for anything—except Jet. The first time he sees the black-haired, golden-eyed beauty he recognizes a shape-shifter like himself—but like no Sentinel he has seen before.

Jet has been trained by the Sentinels' dark counterparts for one mission: to take down Nick Carter. If she succeeds, her pack will be freed. If she fails… But the moment she meets the man with pale green eyes, she recognizes a kindred spirit, a male to match the wild nature of her soul. Together, they could be amazing….

But if they do not betray each other, the people they are supposed to protect will die....

Joe Ryan's lion heart is as rocky and impenetrable as the Arizona mountains he protects. Although no one could ever prove that the muscular Sentinel agent was involved in his former partner's death, Ryan's dark reputation—and ferocious cougar form—spells danger to the unwary.

Lyn Maines is a woman on a mission. The dark-eyed shape-shifter has come to root out corruption, but she quickly discovers she's vulnerable to Ryan's leonine power. As they hunt the rocky peaks, seeking proof of Joe's innocence—or guilt—can she trust her instincts about the proud, tawny loner? Especially when her judgment is overwhelmed by the wilder urgings of her heart…...

At dusk he prowled the Southwest, a huge, sleek black jaguar with startling blue eyes and a man's thoughts. A shape-shifting Sentinel, Dolan Trevi?o projected an intensely animalistic aura that hid the scars of his past. Yet as fierce as his pride was, this immensely powerful guardian needed the intuition and spirit of an innocent horse trainer to find redemption.

The moment he set foot on her ranch, Meghan Lawrence rejected the shape-shifter's protection--but she couldn't turn her back on her family legacy. Her mother had died protecting a magical manuscript that the Sentinels' dark counterparts would now do anything to recover. With an unbreakable will and all-consuming passion, only Dolan possessed the strength to save Meghan. But was she strong enough to tame the beast within?

On a chilly spring night in Grandview, reformed tough guy Gordon Reese makes a final break with his old ways, bidding farewell to his roughneck buddies at The Whetstone Bar. But a vicious killer makes certain that Gordon's farewell will be final indeed. And now the haunting begins.

Gordon's murder has sparked a return to his violent ways, and his embittered spirit is quickly learning how to physically unleash his fury. He hunts down Craig Lusak -- the last man to see Gordon alive -- and begins to terrorize him mercilessly in a rage fueled by vengeance, anger, and unrelenting bloodlust.

Problem is, Gordon may be haunting the wrong man.

When ghost whisperer Melinda Gordon begins to investigate the murder, she discovers a terrified Lusak, who, though desperate to ward off his ghostly tormentor, is secretive about his involvement with Gordon Reese's death. Melinda's interference provokes the killer to begin stalking her, and she becomes the next target of his obsessive homicidal rage. For each minute that the murder goes unsolved, Lusak grows weaker and Melinda faces increasing danger.

In the ultimate battle between good and evil, will Gordon Reese overcome his demons in time to save Melinda from his killer, or will Gordon's unquenchable thirst for revenge lead her to a horrific end?...

Steve Spaneas doesn't have a clue. Who'd have thought that the woman who stumbles her way into his gym, looking and acting so very much like a street person off her meds, is really a CIA case officer whose memory has been obliterated by experimental drugs used by some very bad people? And seriously, who'd have thought that her attempts to untangle the few clues she's got would lead him right into her world of spies and counterspies, death and deception--and holy cow, stockpiled nuclear weapons? But Steve had better figure out who he trusts--his years of experience on the streets, or the heart of a gritty woman determined to reclaim herself--and he'd better figure it out fast. Because suddenly there's a body out behind the gym, surveillance teams lurking, and a series of unsavory goons following the trail of a woman temporarily named Mickey right through his life....
