Greetings from Witness Protection!

Nicki Demere is an orphan and a pickpocket. She also happens to be the U.S. Marshals' best bet to keep a family alive…

The marshals are looking for the perfect girl to join a mother, father, and son on the run from the nation's most notorious criminals. After all, the bad guys are searching for a family with one kid, not two. Adding a streetwise girl who knows a little something about hiding things may be just what the marshals need.

Nicki swears she can keep the Trevor family safe, but to do so she'll have to dodge hitmen, cyberbullies, and standardized testing, all while maintaining her marshal-mandated B-minus average. Nicki learns that the biggest threats to her family's security might not lurk on the road from New York to North Carolina, but rather in her own past.
