The House of Secrets series
Siblings Brendan, Eleanor, and Cordelia Walker once had everything they could ever want. But everything changed when Dr. Walker lost his job. Now the family must relocate to an old Victorian house, formerly the home of occult novelist Denver Kristoff—a house that simultaneously feels creepy and too good to be true. By the time the Walkers realize that one of their neighbors has sinister plans for them, they’re banished to a primeval forest way off the grid.
