I thoroughly enjoyed Red Rising. When I got to the end I thought, "Well. That was a great combo of Ender's Game and Hunger Games. Hey, that sounds good. I'll put that in my review." And then I saw the dust jacket blurb which said the book is: "a mixture of Ender's Game and the Hunger Games". Damn those clever marketing people. And it also goes to show I don't bother reading dust jacket copy! 
 Suffice to say, if you enjoyed either EG or the Hunger Games series, Red Rising is worth checking out. 
 I've done a spoiler-free review of the whole Red Rising Trilogy on my book blog.
