This was a fun, silly, adventure story throwing in lots of references to 19th century classic stories like Frankenstein, Jekyll and Hyde, the Island of Doctor Moreau etc. It has a bit of the "first book in a series, here's a bunch of characters" vibe: the story itself chugs along but isn't that interesting.

There were some clanging americanisms and anachronistic speech that snuck into the prose. I think if you're going to do this sort of pastiche, you could try a little harder to capture the style of the language of the original books.

I don't feel compelled to continue with the series.
