A legend that will change the world. It's been 150 years since the Ahwahnee Indians lived where Yosemite National Park now stands. Their last surviving Chief appears to Elizabeth Hutchings, a twenty-year-old biology student, the very day her parents die. Within 24 hours, she too is clinging to life as his whispers echo in her thoughts. An ancient prophecy has begun. A plague rips through the world's population, taking everyone and everything she has ever cared about. As agents of a mysterious organization called Meadowlark hunt her, she must find the strength to fight the infected even as she struggles to keep herself alive. Just when she thinks she can't go on, a man from her past arrives. He holds the key to understanding the prophecy. If she can unravel its secrets, she not only may change her own fate-but the fate of the entire world.
