I totally didn't realize that Michael Cox's The Glass of Time was a sequel to his first book, The Meaning of Night, but this has just bumped it up to the top of my TBR list. I found this tidbit out in this review of the book. If I wasn't already sold by the fact that the first book was amazing, I would jump right on board when the reviewer calls Cox a "modern-day Wilkie Collins". If you haven't read The Meaning of Night yet and you like Victorian era mysteries with shocking and heart-rending twists, read it immediately.
On a side note, I will be using this as one of the books for my 2nds Challenge now.
Seconding the excitement,
Buy The Meaning of Night and The Glass of Time on Amazon or find them at your local library.
