A cataclysmic love story. Mountains, magic, and an assembly line of stealthy killers. A millennium-old spell that thrusts two people into the heart of danger.

The Alignment is the first book in a new series about two rival families and the people caught between them. Three generations, with a pair of lovers in each: one pair destined, one pair enemy, and one pair tragic.

The destined lovers start it all—if they can manage not to kill each other first.

Trey’s a mountain recluse; Liv’s just made a heartbreaking cross-country move. When he totals her car on her first day in town, he’s in no position to make demands: no police, no insurance company, total control over her car's repair. As if his attitude isn’t enough, she’s inexplicably nauseated when in his physical presence.

Trey’s enemies spot them together and move in on her—through her cabin’s skylight. She’s the one they’ve been waiting for. Trey sentences Liv to protective custody in his own home, but her complaints of nausea are making his drinking habit even worse. If they kill her, he’ll be suspect number one. That’s attention he doesn’t need.

But the stars have their own plan.

With an ancient spell invoked, their problems take a U-turn. He’s heading out for revenge against the family who wronged him, and he needs her help. All she has to do is ingest one homemade dissolving tablet to allow him into her mind–to train her to be just like him.

The answer would be a definite no if she had anything of her world left. If she hadn’t fallen in love with him.
