My 8 year old son has been a bit of a reluctant reader but we've had a bit of a break through recently and he's finally started reading independently for pleasure. I'm obviously delighted and would like to get him something really fun to read for Christmas. He likes graphic novels / comics a lot (he does read the words as well but I think the pictures help him understand and keep his attention).
What's a good one for kids about his age? He likes Vikings, fantasy, space.. but it just needs to be a good story with good art really.
