The Carnegie Medal was just announced today. Tamar by Mal Peet has won.  Here is how the site describes the winner:
This is an enthralling and multi-layered novel that traces the story of two men caught up in secret operations in World War Two. It looks at the negative impact that war has on those involved and on succeeding generations. Guilt and its ramifications lie at the heart of this well-written and serious novel that skilfully interweaves past and present.
