I Know Lucy (The Fugitive Series #1)
by Melissa Pearl
Lucy Tate is on the run. After witnessing the murder of her parents, she's spent five years in hiding — taking on different personas and faking her way through life. The authorities can't be trusted, so she remains in the shadows, always one beat ahead of the man who is forever hunting her. That is, until she meets Zach Schultz, a senior at Monte Vista High and the one guy she can’t bear to leave.
