"Levitation" is an interesting if confusing story about early 20th century magicians and the legerdemain that occurred between them. It's about magicians John Maskelyne, Harry Kellar and Howard Thurston and a particular trick of supposed levitation that was passed between them. It's was fun to see magicians trying to steal each other's secrets, and the lengths they went to to conceal their "powers" from others. The corny stage patter was fun to read as well.
Anyway, like many of Ottaviani's books, there is a lot of information in the notes that explains what does not come across in the artwork. This doesn't say much about the author's storytelling ability, but at least the info gets across in the end.
Is the story of these three magicians worthy of this much attention? Perhaps not, but I found "levitation" at least mildly entertaining.
