A tantalizing and creepy mystery set in the American Southwest, an area which the author brings deliciously to life. We get to travel with FBI Agent Zack as he desperately tracks down a murderous, alien Force before it's too late, with the aid of Eagle Feather, a native American hunting guide. Heart-stopping twists and turns abound. Zack's determination and unorthodox thinking pull in a wonderful cast of characters. I couldn't stop reading till I'd discovered who'd done it, which, of course, wasn't till I'd turned the last page. And even then... I hope for a sequel. I've become too attached to the characters to say goodbye just yet!
