I did a few searches and was not able to find something similar.
I am looking for the name(s) of a sci-fi novel series described to me in passing.
The time of discussion was around 2005/2006 in Sydney Australia, I have been informed that there had been several books written already in the series at this stage. Two key elements that I remember the person telling me is about the story has elements of traveling between universes/dimensions, and contains a weapon that is able to destroy not only the person in the current universe/dimension, but all versions of that person in other universes/dimensions.
Unfortunately I have not read the novel. Does anyone have any idea what this may be?
