Harry Potter is done with life. He did everything and all he wanted was to pass on to the next great adventure. Sadly, rules get in the way of this and he must now find a new way to keep living. It's not all bad though. At least he gets another chance to live life his way and on his terms. Warning: Mentions of attempted suicide and other stuff to come.

OSaBC II : That Which Cannot Die by
LogicalPremise reviews
My AU retelling of the events in ME2, with a completely new take on Cerberus, the Shadow Broker, and the Collectors. Examines the themes of what exactly constitutes death and life, the line between revenge and self-hatred, and how small amounts of light can shine in every darkness. Not a happy ending. Includes my takes on Overlord and LotSB. Rated M for language and violence.
