Readers who liked The Medici Boy and even (or especially) those who didn't may be interested in reading the author's story "Three Short Moments in a Long Life" in a recent New Yorker. The "especially" above is for those who found his writing slack and repetitious. Maybe it was just the narrator.
And for those who are still interested in the MB, I've come across the publisher's Book Group Guide. It includes none of the interesting questions we discussed but … a window into how the other half reads (or to how Astor+Blue thinks they do or should). Followed by an interview with author L'Heureux.
