Slade House by David Mitchell
Readers who have enjoyed David Mitchell’s earlier novels, The Bone Clocks or Cloud Atlas, or who are looking for a haunted house story will be entertained by Slade House. Otherwise, you may be just as confused as young teen Nathan, college student Sally, or policeman Gordon when they open the tiny iron door in Slade Alley and enter the garden of Slade House. The door only appears every nine years on the last Saturday of October. Of course, things are not what they seem, more like Alice in Wonderland than Brigadoon, and eventually they encounter evil twins Jonah and Norah. Not nearly as substantial as his other books, Slade House is humorous and scary, but not very satisfying.
