Charlotte and Tobias soon realize that they are in terrible danger-especially because the head of Witherwood has perfected the art of mind control. If only their amnesiac father would recover. If only Tobias and Charlotte could solve the dark mystery and free the kids at Witherwood-and ultimately save themselves.
