Firepower — Steve Brewer

Can a deadpan hitman save the world from Big Oil?
In FIREPOWER, a hitman named Bob is sent to kill a young woman who invented a regenerative hydrogen fuel cell, an energy source that will make oil obsolete.
Once he realizes what's at stake, Bob helps the scientist escape. They flee across the desert Southwest, branded as terrorists, chased by the feds and by killers sent by Big Oil.
Bob is very good at his job, leaving a trail of bodies as the scientist finds a way to tell the world about the conspiracy.
An action-packed thriller!
