Query: Couldn't put it down, but............

I bought all three books together and it was a "can't put them down" type weekend. Mr. Marzulli did an excellent job of providing me with a captivating story an well as a topic, from a non fiction view, that needs serious thought and prayer, and this makes it priceless. But, it is a fiction trilogy and I was disappointed beyond words in this last book, when most of the characters I had become emotionally involved with, just disappeared without a mention. Phase them out, kill them off, but give me some closure, don't leave me wondering. I enjoyed the new characters, but I did not get as emotionally involved. I did read it as fast as the others, but I think I was trying to hope each new chapter would bring my beloved characters from book 1 and 2 back. I hope he plans to write more and include the old characters. Even with this minor complaint, these are great reads.
