Slade House by David Mitchell
Mitchell does it again in this compact thriller that may or may not be a sequel to The Bone Clocks. Companion piece or spin-off is perhaps a better description. Slade House is tucked away down an alley behind a pub with a small, mysterious iron door that only appears every nine years. Invited in by a strange brother and sister, the unique and unfortunate souls who enter that door are never heard from or seen again. Spanning 50 years from the late 70s to the present, this little novel will make you feel as if you have dropped inside an Escher drawing and will keep you up at night as you hurtle to the conclusion discovering the secrets of this haunted-house story as only Mitchell can reveal them. – Anne Stewart Mark
