Around 2005, I was reading a science fiction book in the middle school library and I was wondering if you could help me identify it. The point of view started as first person and after a few chapters it switched to third person (but was about the same man). I think it was told as a letter, or perhaps a journal that was written while the man was in prison. He was sent there for murdering one of the first aliens to arrive on Earth, but there was a lot of controversy as to whether the law applies to alien species. Eventually, another alien (possible wife or sister) of the same race came down to inflict her own punishment on the murderer, but he always managed to escape her pursuit. In the end, the alien manages to subdue the prisoner to the point of holding a knife to his neck, and at that point they eventually kiss and end up teleporting to the alien world to live together, but unfortunately the man eventually dies because the atmosphere of the alien planet doesn't bode well for his physiology.
Does anyone have a clue as to what the name of this was?
