Just realize Last Days is more for Cobain than about him. It does have many homages to him.

Heavier than Heaven is interesting so far, but I'm not getting carried away by it. I read several chapters and the ending out of curiosity. Courtney Love and Michael Dewitt apparently gave Cross a lot of information, which leads me to doubt it at times. Plus, the ending is completely disrespectful, serving as a jab to Tom Grant by fabricating wishful thinking to knock over some murder evidence, interesting they never mentioned the drugs in his system. Any normal human would've described his death in an objective way without the bullshit.
