sure, the fear books are are part of the bishop trilogies, there are 6 prior to these-stealing shadows, hiding in the shadows, out of the shadows, touching evil, whisper of evil, & sense of evil. always a thief is part of the Quinn novels, there is one before it-once a thief. blood sins is also part of the bishop trilogy, there is another called blood dreams but I'm not positive if it came after blood sins. this info I got from the books themselves, blood sins was written in 2008 so that is the most recent info they had.
