Today I finished reading “Danny Dunn, Invisible Boy” by Jay Williams
Update from the adult Justin: This was the first book I read in the Danny Dunn series, and I devoured them all in any order I could get them.
This was also the very first book I checked out of the public library on a brand new library card from the Penarth public library.
I also learned, a few weeks later, I had the power to fill out a little rectangular card with up to a half-dozen book titles, and have them brought from another library somewhere else in the country directly to my local library so that I could read them.
