CHAPTER ONE

      MAYA BURTON HAD always loved being alone in the wilderness. But after three hours of climbing through steep, dense, shadowy forest, it occurred to her that this nighttime hike through mountain lion territory might dim that love, just a bit.

      It had felt like a good idea, back in Shelter Creek. The odds of meeting a mountain lion on the trail were low, and facing a lion seemed a lot less scary than facing the memories waiting in her hometown.

      But Maya had forgotten that forests in this part of California were full of oak and bay trees that sent their branches arching right over the trail. And mountain lions loved to hang out on branches. Shining her flashlight to make sure she was safe still didn’t ease the prickly feeling on the back of her neck as she passed underneath.

      When she finally reached the edge of the forest, stepping out onto the wide-open ridgetop was sheer relief. She loved studying mountain lions, but she was glad to be in a place where they couldn’t drop on her from above. Maya took in the full moon beaming in the sky, tinting the grassy meadows and scrubby slopes with silver. So much moonlight, she could put her flashlight away.

      They were out here too though. Mountain lions, pumas, cougars, catamounts, ghost cats, panthers...maybe the big cats had so many names because they were so mysterious. Able to exist alongside people without anyone realizing they were even there.

      Except lately the mountain lions in this area had been attacking livestock on local ranches. And people definitely noticed that.

      That was why Maya was here, in the coastal hills surrounding her hometown of Shelter Creek, on a two-month assignment for the Department of Wildlife. She was going to try to find pumas. Photograph them. Count and classify them. Assess the population’s overall health and figure out why they were eating so many sheep.

      But she’d rather not meet any big cats out here in the dark. “Okay, pumas,” she said to the shadowed spaces just past the moonlight. “If you’re out there, beat it. I’m coming into your territory and you are not allowed to bother me.”

      She was being silly. Most big predators would prefer not to run into any humans. Usually people were a meal they didn’t have much appetite for, though once in a while...

      Ugh. Don’t think about that.

      What was wrong with her tonight? Maya spent weeks at a time living in remote wilderness, studying predators. She rarely worried about being attacked. But tonight she was nervous. Maybe because she was used to the Rocky Mountains, and the way mountain lions behaved when they lived in truly wild places.

      Here in Northern California, the mountain lions’ habitat was broken up by ranches,
