I bought this book recently in a 3 for 2 offer in Waterstones. I've been wanting to read it for ages and so couldn't resist this offer.

Synopsis

Nine-year-old Oskar Schell is an inventor, amateur entomologist, Francophile, letter writer, pacifist, natural historian, percussionist, romantic, Great Explorer, jeweller, detective, vegan, and collector of butterflies. When his father is killed in the September 11th attacks on the World Trade Centre, Oskar sets out to solve the mystery of a key he discovers in his father's closet. It is a search which leads him into the lives of strangers, through the five boroughs of New York, into history, to the bombings of Dresden and Hiroshima, and on an inward journey which brings him ever closer to some kind of peace.

Donated this book to either the British Heart Foundation charity shop, the Cancer Research charity shop or the Eden Hospice charity shop in Carlisle.
