Boundary Crossed

by Melissa F. Olson

Published 1 May 2015
After her twin sister’s brutal murder, former US Army Sergeant Allison “Lex” Luther vowed to protect her niece, Charlie. So when two vampires try to kidnap the baby, it quickly turns into a fight to the death—Lex’s death, that is.

She wakes up to two shocking discoveries: she has miraculously survived the fight; and baby Charlie is a “null,” gifted with the ability to weaken supernatural forces...and a target for creatures who want to control that power. Determined to guarantee her niece’s safety, Lex makes a deal with the local vampires. She sets out with the mysterious—and undead—“fixer” Quinn to track down whoever’s responsible for the kidnapping, sharpening her newfound magic skills along the way. But the closer she gets to the truth, the more dangerous her powers become.

Boundary Crossed is a dark, thrilling journey into a world where the line between living and dead isn’t nearly as solid as it appears...

Fitting into the Old World isn’t going very well for Boulder boundary witch Allison “Lex” Luther: she may have earned a place in a vampire’s service, but now it seems as if every supernatural creature in town has found a reason to hate her. And when Lex and her partner are assigned to investigate the suspicious disappearance of two vampires during the night of the full moon, they find themselves with more questions than answers.

Was it murder…or mutiny?

The crusade for answers will lead Lex all over the Colorado Old World, from a prison cell for a broken werewolf to a haunted Denver brothel. And when Lex determines the responsible party, the hunt is just beginning: something has been awakened in Boulder, something as old and powerful as it is terrifying. Only the woman with death in her blood can stop what’s coming.

Something wicked is at work in Colorado’s supernatural community. Vampires are being paralyzed or killed with poison…a weapon favored by witches. This offense threatens to break apart the already-fractured alliance between witches and the undead.

The state’s cardinal vampire, Maven, summons boundary witch Allison “Lex” Luther to stop the killing before it ignites a war. Lex has barely started investigating when she gets another surprise: the biological father she’s never met arrives on her doorstep. He has answers to all of Lex’s questions about her bloodline, but getting those answers could mean betraying the life she’s already built.

Then the next vampire is poisoned—and this time it’s Maven herself. The new evil that hunts Lex is powerful and ruthless enough to stop the strongest supernatural creature in the state. In order to find such a killer, Lex will have to face down her own birthright and call on every ally—both living and dead.

Months after her battles in Wyoming, Allison “Lex” Luther is still struggling with the aftereffects of the psychic attack she suffered—and with the new developments in her own magic.

Then Lex’s boss, the cardinal vampire of Colorado, passes along a strange request from her counterpart in Atlanta. Hundreds of Civil War spirits have abruptly vanished in Beau Calhoun’s territory, and he wants Lex to figure out why. In exchange, Beau can help her understand boundary magic, which runs in his family line as well.

Despite her trepidation, Lex journeys to the Deep South, where she discovers that ghosts are everywhere…and that her host’s intentions are more complicated than he promised. It seems his teenage descendant is being hunted, and both Beau and Lex fear the young woman’s boundary blood may have made her a target.

With Atlanta’s history looming over her every move, Lex will have to face Beau’s ghosts—and her own—to prevent a boundary magic attack she never dreamed possible.
