After breaking free from the clutches of Heaven, Atticus and Bentley took Frances and fled to Jericho, Washington. It wasn't the best place in the world, but it was the first that came to mind. Heaven knew Atticus' registered Earthly address, but even if they came knocking again, Atticus could always keep the door locked against them. If they painted enough deterring spells and wardings all over the house, they would be able to keep Heaven at bay for a while. They could knock and yell and shake the earth all they wanted, but nobody would be able to enter the building unless the wards were broken.
