Holland Sellers. She's your average senior in high school with a high GPA and multiple jobs. She has dreams to go to college and make her way in the world. There is one thing about her that is different, though: she owns a car service. For drunk teenagers. The Designated Driver Service is the brain child of Holly. She goes to a different party each Friday night and drives kids home. It keeps drunk kids from crashing cars, and sober people from getting hurt. Her reasoning? Holly is an orphan. She has been for eight years of her life. Her parents died because of a drunk driver. So now, she has decided to change the fate of her town for the better. Until, in the weeks before her eighteenth birthday, she gets a new piece of information about her parents' deaths that turns her world on its head. Now, she has custody of an eight-year-old brother she didn't know existed. She has to navigate the waters of change and keep her grades afloat all at the same time. How will she do it? And don't mention the egotistical jerk known as Briggs Huxley or her middle school crush, Steven Booker. With all the other stuff going on, she doesn't have time for romance. Right?
