Three children playing in a barn. A deadly accident...and then a void. When Lorene Whitten returns to Garland, Kansas, because of her father's illness, she is shocked to find that her childhood playmate, Cassa, has been missing all of this time. The Lander farm evokes haunting, ghost-like memories of her little playmate, as if Cassa were beckoning to her from the grave. Lorene starts asking questions and encounters resistance from the close-knit group of three long-time friends and town leaders who call themselves the Knights of Garland, of which her father is a member. Ethan Lander, the boy who was with them in the barn that day, offers to help her locate Cassa. But Lorene wonders if his real goal is to prevent her from finding out the truth. And what of her own disturbing memories? Lorene must find out what really happened that day. Was Cassa the victim of an ill-fated accident, or murder?
