I'm looking for good books (fact or fiction) about vikings for young children - under 8.

Pirate Diary - The Journal of Jake Carpenter by Richard Platt, illustrated by Chris Riddel. (I think this is good. The illustration is very good (and it won a Greenaway medal for the illustration).

A Flat Stanley collection. (I don't think it's much good. My son enjoys it though.)

And I'm about to start re-reading everything by Fred Vargas.
