Mel Odom, who has written more books than seems possible for one human not named Patterson, turns in a review of Alex Van Helsing that keys in on the literary angle:
Interestingly enough, Henderson not only ties the vampire legend to Dracula, but also to Frankenstein, and he’s set the series near Lake Geneva, where Mary Shelley first wrote the famous short story that would later become a book that will live on in the annals of horror – oh yeah, literature, too.
The literary history captivated me. The story of that weekend where Mary Shelley (then 18 years old), Lord Byron, John Polidori, and Percy Shelley has been mined by several writers, but this is a new twist. The two literary histories, vampirism and Frankenstein, are inextricably bound in this book, and it looks like that’s going to be a staple of the series.
