The Bloody Ripper is set in Victorian England at the same time as the Jack the Ripper murders. In addition to the murders, people are going missing, taken for use in experiments that are never really detailed.
This book is quite short on detail when it comes to all of the plot points. Coming in at 199 pages for the Kindle edition, there just isn’t enough room to cover all of the details that crop up in the story, leaving an overwhelming feeling of being rushed through. On top of that, the plot is shaky at best (alien vampires kidnapping some people, killing others, and framing someone for the murders) and it’s not particularly well written (bland prose, bland characters, and whoever edited the Kindle edition needs to seriously re-evaluate their chosen career).
This is one of three tie-in novels for The Leopard King Saga, which also seems to involve a weird mash-up of history and fantasy (a magical leopardess in Ancient Rome). That is about as far as the relationship between them goes, as the Saga is set entirely in Ancient Rome.
I really wanted to like this book, but when all is said and done, the only good part was reaching the end.
