When inventor Allyson Levitz wakes up fifty years in the future, the world has been ravaged and everyone she knows and love could be gone.

As she makes her way out of New York City, she realizes everything has changed. Humanity has been nearly wiped out, and those who remain are altered and lives in tribes based on their mutations. As Allyson tries to get to Albany in hopes of finding a remnant of her family, she sees the once familiar landscape has changed-old traces of civilization disappearing as nature reclaims what was once taken. As she makes contact with each of the tribes, she makes new friends. Each one becomes critical as the races turn on her, demanding the information locked in her brain. Even in the most difficult circumstances, hearts recognize each other and a bond is formed. Frightening in its intensity and suddenness, she fights it with all she has.

Together with her friends, she must find a safe place to live. Not an easy task, when it seems she is at the top of everyone's most wanted list. If she can just get to her family's land in Albany, there is hope in the form of a Doomsday shelter built by her uncle. When attraction becomes too overpowering, will she give in to temptation?

If anyone gets a hold of her and the information she possesses, the world will be thrown into a power struggle that could destroy the population that remains. And if she loses control and gives into her feelings, she could be forced to choose a side.
