A History of Madness is a good and solid sequel to A Touch of Death.
You need a vampire to catch a vampire.
One of the most anticipated releases of January 2019 was The Winter of the Witch as the conclusion to the Winternight trilogy. If you have been waiting a while. It was certainly worth the wait. While I didn’t end up loving this book as much as I did the second, it is still a very worthy ending to the story.
