I am Fantasy Fanatic but would like to read more SciFi. A couple years back I was searching for some SciFi and extracted a list of potential candidates from this site. Since then I have lost my list. It is driving me insane that I can't find one specific book that struck my interest. It was briefly discussed on of the years best threads. Knowing that you would think I could find it, alas no. It's about 2 worlds that are near each other and one of them is dying. I believe they send someone to the dying planet either to find out why or to help whomever is on it.
