This is a historical horror/thriller story revolving around Robert Louis Stevenson, the story of Dr. Jekyll & Mr. Hyde, and Jack the Ripper. It alternates between 1880's London and "present day" California. My favorite parts were in the 1880's where Stevenson creates the story of Dr. Jekyll & Mr. Hyde and deals with the consequences. The present-day story revolves around Rafe, an environmental scientist who is working to save the coyotes and stumbles across a mysterious steamer trunk.
The part with Stevenson is intriguing and suspenseful and was hard to put down. But, the present day part with Rafe is a bit tedious and took a while to get going. I kept trying to figure out how it connected with the Stevenson story but was more interested in getting back to the 1880's. The narration is well done even though the accent irritated me a bit.
This is a brilliant premise for a story but lacks a bit in the execution. Overall I enjoyed it and recommend it to fans of history and horror (as combining the two is a bit unusual).
