Late in making this thread, but I just finished "Red Rising" by Pierce Brown.

It was a slow start, and veered way off course from where I thought it was going, but I really enjoyed it. I'd definitely recommend to anyone that is interested in 'Battle Royale' or 'Hunger Games' style stories. This one has a little more grown up context than those two however.

Edit: Trying to finish the last half of "Caliban's War" from the Expanse Series - I sat it down far too long ago and may need to start over. o.O
