Captain Jack Harkness is a fixed point in time and space. If you kill him, he'll just keep coming back to life. Before Jack had Torchwood, even before he was a con man, he was something else entirely; a time agent, using a vortex manipulator to jump through space and time. He wasn't the only one, however, and when an old friend of his saves a girl's life, Jack must discover if she is a valuable ally or an extremely dangerous enemy. NOTE: This is a work-in-progress. I publish chapters as I finish them, so follow this account to get updates on when the next part is available.
