I don't think you will find what you are looking for in any book. The successful implementation of financial models is very much tied to the pricing and risk system it is being used in. The latest and greatest libraries are developed by some large investment banks, possibly certain buy side shops. So you would have to learn that on the spot somehow. I don't think that people writing textbooks know much about systems implementations, nor about industrial strength financial modeling for that matter. Put it another way, it is exceedingly rare that someone siting behind a system with good understanding, writes a book about it.
