Adrenaline Rush (Unabridged‪)‬

A madman with a mission is kidnapping groups of thrill-seeking high school seniors across the country, and it's up to Christy to stop him.

To do so, she must take on a fearless alter ego and infiltrate a group of adrenaline junkies bent on pushing life to the limit. Death-defying stunts are only the beginning: Two groups fit the profile, and Christy must discover the real target before it's too late.

If she chooses the wrong group, more people will disappear. But choosing right puts her as the prime target, with no guarantee that she'll get out alive.
