At the end of '4 Empty Graves', Martin Teebs finally got his happily ever after....or did he? With nagging doubts about the six months between the end of Old Lincoln Days and his final trip back in time to Lincoln, Martin must examine exactly what became of Kevin Barrow and Trisha Davis, the two young people who looked suspiciously like Billy the Kid and Rosita Luna? With the possibility that he might be implicated in their disappearance, Martin makes a desperate trip to modern day Lincoln, enlisting the help of Steve from Capitan, in order to tie up any loose ends that might have the past (and the FBI) coming to get him. From the past, Rosita implores Billy to try to reach Martin, if only to let him know he's about to be a father again. Billy's trip takes him nowhere near Martin, but back to the most sad and dramatic moment of his life. Will he learn from reliving the tragedy, or will his trip only leave behind pieces of himself? 'Pieces of Us' is the harrowing 7th installment of the 'Back to Billy' saga!
