@bigimp I've already read Kill Who You Want, I was voting on it a chapter at a time so you probably didn't notice it....
To answer your questions, I must say that all of your books have very unexpected twists and turns which keeps the reader completely hooked to the story, and as for my favorite, I loved The Painted Altar the most, especially because of the way you so wonderfully described the emotions and life of the characters living in varying times. Although I must mention The Third Shadow too, the way in which you told so many possibilities that could have happened in the same situation, all of them very probable, is amazing.
And my favorite authors include Sir Arthur Conan Doyle, O. Henry, Jane Austen, Thomas Hardy, Oscar Wilde, etc.
Sorry for the long reply xd and all the best for your future!!
