Amazon.com description: Product Description: Are you a Jimmiehead, or are you still using one of those old-fashioned smartphones?

A Jimmie is a tiny microchip, that when painlessly implanted into your brain, magically transforms your eyes and ears into the ultimate hands-free device. No more fumbling with fragile phones, loose earbuds, or clumsy controllers. Watch movies without looking at a screen. Shoot video through your eyes. Text with your brain waves. It tracks your location, monitors your health, and even comforts you when you're lonely. Plus, it drives your car! 

Every teenager wants a Jimmie, except 16-year-old Amy, who detests technology in any form. She is particularly disgusted by how easily people are manipulated into wanting one. 

Like smartphones, Jimmies spy on your cyber activity, but being hard-wired to your brain also allows them access to your personality. They can read your innermost thoughts and eavesdrop on your deepest feelings. What Jimmieheads fail to consider is that the wireless devices don't only transmit, but receive--allowing it to control what users see, hear, and feel. Regardless, the hi-tech device becomes a worldwide sensation. 

But when thousands of teenage Jimmie users mysteriously vanish, foul play is suspected by the billion-dollar corporation that manufactures the device. Immune to Jimmie's influence, Amy embarks on a quest to find the missing teens. Her search ultimately reveals a connection between the bizarre disappearances and the Fun Zone--a spooky, old amusement park that's been dark for 50 years.
