>Also, just remembered, when I was a kid I loved to read the
Hardy Boys series, and (dating myself),
Emilio Salgari's wonderful Pirate books (Sandokan, Corsair Pirates), and Edgar Rice Burroughs's Tarzan books, and anything by Jules Verne.
Also, there are lots of othr good books by Burroughs, like the Barsoom series (I think the first one was "A Princess of Mars"). I am not sure how appropriate that would be for that age, though.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
