I really enjoyed this rendition of the Holmes story. Since remakes of the characters themselves are a bit overdone at this point, it was fun to see the idea of Holmes and Watson's ancestors. I've seen female Watsons before, but never female Holmes (not saying they aren't out there, but this is the first I've seen), and I think it's a much more challenging character to write. It's pulled off well in this one, in my opinion. Definitely a fun, quick-paced read.
