Mystery about a kidnapped girl

I remember the beginning of the book a girl was sick and her mom went into the doctors office to get a prescription. During that time a man unlocks the door and takes the car with her in the backseat, she wakes up and the car is parked in front of his house. I cannot remember anything after that but I know it was an old book released before 2013 if that helps.
thanks

Found.

Sounds like Girl, Stolen (2010). Summary:

"Sixteen-year-old Cheyenne Wilder is sleeping in the back of the car while her stepmom fills a prescription for antibiotics. Before Cheyenne realizes what's happening, the car is being stolen."

Thank you so much that is the one!

Happy to help. Enjoy reading it again.
