The Red House   by Mark Haddon

This is probably the most boring book I've ever read.

The families of a brother and sister spend a week together in a house after the death of their mother, and it is a day-by-day account of many of the mundane things that happen. It is spiced up a little with the coming-out of a gay daughter who makes a pass at her opposite number, and the main brother having something of a mid-life crisis takes up jogging, twists his ankle, and there is an over-dramatised do-or-die rescue effort.
