The outliers

Wylie and her best friend, Cassie, got into a fight a week ago, but the first contact they make again is Cassie's simple text asking for Wylie's help. Offering only cryptic clues as to where she has gone, Cassie seems to be not only in trouble but danger this time. Needing Jasper's help--the boy who once drove Cassie over the edge--Wylie sets out north to follow her friend's trail in the dense woods of Maine. However, finding Cassie may only be the beginning.
