The Ghost of a Tree Remembered

Liz and Nick should have been dressed in their costumes for the Living Cemetery but were late so instead carried them in their bags. No problem the Drama Club director assured them. Take this key and change in the pavilion; just be sure to give it to me immediately when you return. The old-fashioned key didnt look as if it would fit any lock they had ever seen. In fact it looked almost magical. But as soon as Liz touched the key to the lock the cemetery had vanished and she found herself on the Old Plank Road. Liz and Nick were still in Downers Grove but the year was 1863 at the height of the Civil War. Why were they there? What were they supposed to do? And how in the world would they return to their own time?Liz and Nick should have been dressed in their costumes for the Living Cemetery but were late so instead carried them in their bags.
