No, that's not the end of the sentence. PBS didn't name Boys of Steel: The Creators of Superman, though I'm sure given the chance, whatever they would've suggested would've been great.
What PBS did kindly do is name Boys of Steel a "best book for boys - middle readers."
I wonder if just having the word "boys" in the title is enough to merit such an honor? If so, my next book might be renamed Beach Read of Steel.
