Extrem Laut Und Unglaublich Nah by Jonathan Safran Foer

A nine-year-old boy who lost his father in a terrorist attack discovers a mysterious key and embarks on a citywide quest to find the lock it fits, meeting strangers, uncovering family secrets, and confronting the tangled emotions of grief; the search becomes a moving exploration of memory, communication, and the ways people cope with loss, told through a tender, inventive narrative that mixes youthful imagination with adult pain.
