Shock Point by April Henry
When Cassie Streng is abducted by two men in a white van right in front of her own house, she can’t at first figure out what’s going on. When her mother comes outside and does nothing to stop the men, confusion turns to panic. When her stepfather, Dr. Rick Wheeler, enters the picture, things suddenly become clear. Rick planted drugs in Cassie’s room, convinced her mother that she needed more help than they could give her to straighten her out, and is shipping her out to a school/prison in Mexico
