Tessa had known Kevin Idle growing up. No one she knew was more gifted, but no one she knew was more useless either. He'd become a stereotypical loser in high school: stoner, smoker, petty thief; a boy with an A plus brain and a C minus average. He'd got into serious trouble with the law and was sent to military school by his father. He ended up joining the Navy and becoming a SEAL, but was expelled for smoking weed. He reluctantly takes on the role of Tessa's protector, reluctantly because he has gangs of killers after him, as well.
The two go on the run, and are constantly beset by assassination attempts as they try to determine who is after her, and look for a way to reproduce the battery prototype.
Will they survive long enough to bring the critical new technology to fruition?
