Seth (Cyborgs: More Than Machines, #5) by Eve Langlais
His mission: Blend in with the humans. Save the cyborgs. And of course, seduce the girl.
An excellent athlete who is highly intelligent, charismatic–without
modesty–and handsome too, Seth has it all except for the girl. But not
for long. Like it or not, he’s determined to win her heart–and get in
her pants. So what if it means letting the military replace a few parts
and becoming the world’s first cybernetic spy? Cool missions, a hot
chick, awesome toys, it all sounds like a dream come true until the
military decides to terminate their billion dollar project.
But they didn’t count on their project soldier fighting back.
