Publisher's Description
Simon Orwell is a brilliant student whose life has taken a series of
wrong turns. At the point of giving up on his dreams, he gets a call
from an old professor who has discovered a breakthrough in a device that
would create unlimited energy, and he needs Simon's help.
But once he crosses the border, nothing goes as the young man planned.
The professor has been killed and Simon is assaulted and nearly killed
by members of a powerful drug cartel.
Now he must take refuge in the only place that will help him, a local
orphanage. There, Simon meets Harold Finch, the orphanage proprietor who
walked away from a lucrative career with NASA and consulting Fortune
500 companies to serve a higher cause.
With Harold's help, Simon sets out on a quest to uncover who killed the
professor and why. In due time, he will discover secrets to both the
worldchanging device and his own unlimited potential.
