Tamara Umbra had been training for doomsday for as long as she could remember. When she is accidentally locked inside The End Timers luxury fallout shelter, everything begins to fall apart. Trusting a mysterious voice in her head, she makes a harrowing escape from the end times shelter.
While fleeing from police and the FBI, she must face down the group behind it all to find the source of the telepathic voice whispering about an end times conspiracy and helping evolve her telekinetic powers. With the help of an unlikely sisterhood that develops from a botched carjacking, Tammy must survive long enough to solve the mystery of the voice and uncover the truth, all while a supernatural agency from a secret society is hell-bent on bringing her in dead or alive.
