The Keystone (Paperback) (ISBN-13: 9781736538708)

They hunted her mother. They abducted her father. If Grace can't uncover the secret of her family's alien past, will she be next?

Grace is unique. She tries not to draw attention, but most teens don't have naturally green hair, live in a van, and change schools every couple of months. When people around her start dying and the federal government turns up asking about national secrets, she knows she is in over her head.

Grace has to find the truth. With her brave new friends rallying behind her, she sets off on a daring adventure. But will she risk her new friends to reveal an old family secret that has already cost her everything she loves?
