Star Wars: Dark Underworld

in 4267 ABY a young Jedi Padawan manages to survive a Jedi Purge and finds himself raised by Mandalorians. Years later he makes a name for himself as one of the best bounty hunters in the Galaxy, does he have what it takes to survive a Galaxy ruled by a Sith Empire, Rouge Warlords including a Sith Warlord that had killed his master so many years before? I'm bad at summaries.
