Titanium Noir

Like all the best SF, this works as an interrogation of our present day circumstances. On one hand it's a Chandlerish tale full of menacing thugs with guns and the hero getting banged on the head and waking up somewhere else, on the other it's a commentary on the current sociopolitical state of the West, with the Titans standing in for the billionaires who run our world. It's also pithy on the ongoing consolidation of wealth away from the young towards the older generation:

“As if there can't be new things because the old ones aren't going away”

There's a fair bit to chew on in what's ostensibly a noir romp, but the joy is that it works on both levels, and you can read however much or little as you like into it and still have fun.
