Interface - The Naravan Chronicles, #2

When Gina Xanacovich's nanotech research leads to murder and death threats, her father hires private mercenaries to protect her. But Johan "Alex" Alexander proves to be as dangerous to her peace of mind as the threats against her life. And his seductive voice and irritatingly calm presence keep Gina on edge, wanting more from him than just a bodyguard. Alex has a rule. No romantic relationships with clients.
He and his partner stick to that rule to save lives. But his newest client, the fiery engineer Gina Xanacovich, turns all Alex's intentions upside down. To uncover the threat to her life, he has to ignore his feelings for her. Unfortunately, that proves harder than any job he's done before. Author's NoteInterface was originally published as part of a short story anthology, DREAM QUEST, in October 2003.
Interface has been rewritten and extended into novella length and includes scenes not included in the original story.
