Or
Time Windows by Kathryn Reiss
Miranda can’t explain her fascination with the dollhouse in the attic of her family’s big, old house–no one would believe that she has discovered a time machine that allows her to see into the sometimes frightening lives of her house’s previous occupants. But when her family begins to mirror the dollhouse family’s ugly behavior, Miranda must act quickly to prevent disaster. Reiss puts a new twist on time travel in this suspenseful first novel
