Endings

My favorite book, The Cross Examination of Oliver Finney, has my ideal ending. It's hard to describe, unexpected... there will be no series of this book, but the author uses some of the characters in his other books, so it is somewhat connected.

Also, it coincides with another book (The Cross Examination of Jesus Christ) that has different "codes" hidden within it that one of the protagonist uses to communicate to the outside world, as well as other ways to communicate through algorithms and such. These codes hidden within the second book would pretty much go unnoticed if you were to read it without reading the first book I mentioned.
