Circle of Flight (Ellie Chronicles)

It is a time of profound change for Ellie Linton. Enemies are everywhere. Some come crawling over the hills others drive in and knock on the front door. Sometimes her friends are there and sometimes they are not. Ellie fights every inch of the way. But when courage and imagination are not enough, when she is trapped and helpless, Ellie must face the end of life as she knows it... standing alone, sustained only by her own strength.
