From the internationally best-selling author of Measuring the World and F, an eerie and supernatural tale of a writer's emotional collapse

"It is fitting that I'm beginning a new notebook up here. New surroundings and new ideas, a new beginning. Fresh air."

This passage is from the first entry of a journal kept by the narrator of Daniel Kehlmann's spellbinding new novel. It is the record of the seven days that he, his wife, and his four-year-old daughter spend in a house they have rented in the mountains of Germany--a house that thwarts the expectations of the narrator's recollection and seems to defy the very laws of physics. He is eager to finish a screenplay for a sequel to the movie that launched his career, but something he cannot explain is undermining his convictions and confidence, a process he is recording in this account of the uncanny events that unfold as he tries to understand what, exactly, is happening around him--and within him.
