Thing 1 is currently reading Mary Pope Osborne's Dinosaurs Before Dark, from the Magic Tree House series. I only checked out one of the books to begin with because I was unsure of how receptive he would be, but he seems to REALLY like it, so I am going to see if I can't get ahold of the next few books in the series from the library for him. :)
So next week will probably have many more books added to it.
(and I tried to find a good picture but failed miserably...)
