Earlier this year, the Junior Library Guild chose Boys of Steel: The Creators of Superman as one of their titles; now they have reviewed it. They charge to access their reviews online so I hope you'll take my word for it that the following excerpts are from the their October/November print catalog:
"...fast-paced, exciting, and carefully researched..."
"...impressive, thorough, and highly readable afterword..."
"This fine book is a must-read..."
Also, a librarian with pink hair wrote that the book got her "all choked up."
