Phase Shift (Paperback) (ISBN-13: 9798227131652)

Sixteen-year-old Oliver Mitchell was always a loner, content to spend his time taking care of his younger sister and hard-working mother. When his sister is the first in a string of impossible disappearances, he reluctantly teams up with his secret crush, Lizzy-and her boyfriend-to solve this mystery and bring their loved ones home. As more people are taken from their small Minnesota town, they realize these kidnappings are the first wave of an invasion of telepathic alien creatures. As they keep investigating, Oliver comes to realize that the kidnappings aren't completely random-and he's the aliens' next target.
