Tuned Out — Mari Kesselring

Bridget is not happy. She's on a long road trip, squished between two of her annoying cousins. So she slips on her high-tech headphones and tunes them out. Problem is, she tunes everything out, including where she's supposed to meet up with everyone while visiting Mount Rushmore. With her phone battery dead, Bridget is left to find another techie way out of trouble.
