Children of the Atom is worth reading; it’s a collection of a series of short stories about genius kids. The first story, “In Hiding,” is a classic, and I think fairly important to the field even though most of it is probably old hat by now. The series as a whole prefigured Nancy Kress’s “Beggars in Spain” (and to some extent the novels that grew out of that), as well as the entire idea of the X-Men; “outcast genius kids find each other” is a classic sf theme, and “In Hiding” (1948) wasn’t the first such story nor the best known (cf Slan, 1940), but it was imo one of the best. The Shiras stories after the first one aren’t as good and aren’t as important, except that the plot resolution of the overall story [or rather, the book] is one that I see as extremely rare in sf on this theme. Also of possible interest: Wilmar H. Shiras was one of the few women writing sf at the time, though she didn’t write very much sf and wasn’t nearly as well-known as some of the others.

I am hereby flabbergasted that you’ve read all but one of those books.
