Night Thunder — Ruby Jean Jensen

One hundred and thirty years after a strange religious cult is hunted down and a sycamore tree is planted over their graves, the tree is cut down by land developers and an unspeakably evil force reawakens.

It is 1865 and as the Civil War rages across the land, an 11-year-old boy awakens to the sound of thunderous drumbeats. Four days later, his mother is dead, and a strange cult of religious wanderers have been brutally murdered by the terrified local farmers. In 1995, a gnarled sycamore tree planted over their graves is uprooted by bulldozers--and evil arises.
