Thanks for the recommendation. It's hard to predict which books might attract my kids; I think for now we'll just go with the ones on the list that we happen to own.
I'm also trying to get both kids to read more non-fiction, so I've put a bunch of popularizing history books out on ds13's dresser. It seems to be working -- he picked up 'The Ghost Map', about the discovery of the cause of cholera during an outbreak of the disease in London in 1854, and has pronounced it 'officially cool'. He wants to use it next year to compete in History Day.
