The Callahan's series (Books 1-4) by Lora Leigh [epub,mobi]

Midnight Sins:
His name is Rafer Callahan. He was a kid from the wrong side of the tracks who fought through life the only way he knew how: with his fists. But Rafer never meant to bring any harm to Cambria Flannigan, the girl—the lover—whose sister he’d been unable to save…

Cami lost her sister in the brutal murders that rocked her hometown so many years ago. Some still believe that Rafe, along with his friends Logan and Crowe, were involved. But how could Rafe—who haunted her girlish dreams, then her adult fantasies—be a killer? That is the question that keeps her up at night.


Now a prosperous ranch owner, Rafe is trying to build a new legacy for himself. It’s finally time to settle the score with Cami—and make her his. But old wounds open up with a series of new murders…and each of the victims has a connection to Rafe, Logan, and Crowe. With suspicion, fear, and loyalty tearing her apart, Cami is once again at risk of losing her heart—or her life.

Deadly Sins:
Witnesses to a shocking crime, three men must face the dangers of the past to unlock the passion in their hearts…
Logan Callahan has fought hard to forget what happened that fateful day, so long ago. But every night he tries to sleep, he relives the nightmare. Every time he closes his eyes, he sees the woman whose life he could not save…
A newcomer in town, Sky O’Brien is a mystery to Logan. Like him, she is a night owl. Like him, she is fighting her own demons. Like him, she hides a secret in her eyes—a fire that consumes him with every glance. Could she be the one to heal him?
When Logan’s ex-girlfriend is brutally murdered, his past implicates him as suspect—and his new neighbor Sky may be the only person he can turn to. Together, they share an attraction that can’t be denied. But as he searches for the real killer, he discovers that Sky is tracking down a murderer too—and she intends to use him to do it…

Secret Sins:
Sheriff Archer Tobias has watched the Callahan family struggle to find peace and acceptance in the community—despite the murders that continue to haunt them. But his darkest suspicions grow worse when Anna Corbin, a member of one of the country's most influential families, becomes the next target…
Anna knows she’s in danger. She knows she’s on a trail of secrets and lies that could lead to a dead end. But no matter what, she’s determined to learn the identity of the killer—even if it’s someone she loves…
Torn between duty and desire, Sheriff Tobias cannot allow Anna to put herself in the path of a deranged murderer. But as the investigation pulls them closer together—and deeper into the nightmare—he realizes that he cannot save her from this legacy of blood and vengeance…without putting his own life on the line.
