The messages from the Riprap man change. Instead of warning of deaths, they warn of earthquakes.
Nothing holds the Riprap man back from his true element: Earth.
Can Portland survive even a little earthquake? How can Tara stop him? Can she bring together an alliance of witches and community members strong enough to defeat the earth spirit?
"Circle of Earth" - the fourth and last book in The Witch's Progress series - brings enemies and friends together, but at what cost?
Be sure to read all the books in The Witch's Progress, starting with "Circle of Air."
