I finished reading this to RDC last night. I am gratified that he liked it so much.
Next up I think might be Jackaroo, though Melissa found it so poorly done that I wonder if it will hold up to RDC's ear. Maybe The Giver, although that doesn't hold up for me. He does need some Voigt (that is, I want him to know some Voigt), but I am dubious how he will feel about the Tillerman saga, when it is so saga-ish. He would like Dicey (read, he had better like Dicey) but Homecoming might be too young or repetitive, although he grew up along their trek route just as I did. (No, he grew up west of New Haven, whereas I can remember when the Old Lyme A&P had the outdoor conveyor belt the Tillermans encountered, and I laughed when they entered Sound View and "everything looked very clean," because Sound View was as scary to me as any inner city when I was a child. Can you say "sheltered"? I knew you could!) Maybe The Runner? Maybe Island of the Blue Dolphins or Julie of the Wolves or My Side of the Mountain for Independent Wilderness Living, despite the Canine Mortality. Which is a factor in The Runner as well.
Me, I'm listening to Across Five Aprils. I should have listened to a sample first, though anyone following George Guidall would compare badly so maybe I should show the narrator some mercy.
