I got a letter from the good folks at Michigan State University Press letting me know that Challenge Accepted has been featured in Jim Agnew's Literary World in his "Daily Picks" section of books.
Agnew is a book reviewer and according to his web site at http://www.jimagnew.net/, "Jim also is a world-class literary researcher whose clients have included Vincent Bugliosi, Dan Moldea, Bill Zehme, Gus Russo, Bill Kurtis, Jonathan VanMeter, the late Bill Roemer, Nick Pileggi and Nick Tosches. The late Pulitzer Prize award winning columnist Mike Royko referred to Agnew as " the finest researcher of crime in America." He has been profiled in the Chicago-Sun Times, The Chicago Reader and a chapter in the Nick Tosches Reader (DaCapo)."
Thank you Mr. Agnew.
