Saw Mickey 17, a sci-fi comedy, based on Mickey 7, by Edward Ashton, which I read and thoroughly, thoroughly enjoyed.
I am fascinated by stories of identity and the meaning of selfness.
Mickey Barnes (Robert Pattison - of 'Sparkly Vampire' infamy) is running from a loan shark and, to escape the price on his head, signs up for an off-world trip to a new colony.
The only way he could get selected is as an 'Expendable' - which is exactly what it sounds like: he gets all the suicide missions...
